B.2 - 2011 THE ROYAL COLLEGE OF VETERINARY SURGEONS CERTIFICATE IN VETERINARY DIAGNOSTIC IMAGING1 SPECIFIC GUIDANCE NOTES FOR CANDIDATES [These notes must be read in conjunction with the B1 General Guidance Notes to Candidates] MEMBERSHIP OF THE ROYAL COLLEGE OF VETERINARY SURGEONS 1. It is not a requirement of the Veterinary Diagnostic Imaging Board for candidates entering for the Certificate to be Members of the Royal College of Veterinary Surgeons (MRCVS), although they will need to hold an approved veterinary degree. AIM 2. This Certificate is aimed at: a. Veterinary surgeons in private practice (Approved Practice route) at which ideally 500 or more cases are radiographed per annum and where the candidate is responsible for the radiography of at least 250 of those cases. b. Veterinary surgeons undergoing a full-time imaging residency-type programme at a veterinary school or other approved centre (Approved Centre route). IONISING RADIATIONS REGULATIONS 3. It is a legal requirement that all veterinary radiography is performed in accordance with the Ionising Radiations Regulations (SI 199:3232 [IRR99]). 4. It is essential that these regulations are observed in all Approved Practices and Approved Centres and that all radiographs submitted as part of the examination show evidence of compliance with the recommendations of the Guidance Notes. Overseas candidates are expected to be conversant with these regulations. APPROVED PRACTICE ROUTE Specific Experience 5. 1 Before applying for Final Approval to sit the examinations, candidates must have spent a period of time gaining experience, which must be approved by the Board. The minimum time gaining this experience is two years in full-time employment. If however the candidate’s imaging caseload is less than that specified in 2a above, the period of time needed to gain adequate experience for this Certificate will be greater. Previously the Certificate in Veterinary Radiology. The change of title came into effect from 1 November 2003. 1 6. Candidates following the Approved Practice route will not be permitted to apply for Final Approval of Experience until they have been Members of the College or held an approved veterinary qualification for at least three years. 7. The Board has discretion to increase the requirement for experience, above the minimum specified, for any candidate where it is considered that additional experience will be of benefit. Additional Experience 8. If there is a shortfall in a candidate’s workload of small or large animal cases, arrangements will need to be made to gain additional appropriate experience. The adviser may be able to give guidance with regard to planning in order to gain sufficient experience for the examination and making arrangements to spend time in other centres. Candidates are advised to check whether or not an establishment they plan to attend will allow original radiographs to be used in their casebook. Although use of original films in the casebook is optimal, if this is not possible, candidates may include good quality copy films in their submitted work (N.B. original films or good quality copies can be submitted with the 10 short case reports, but copies are not suitable for submission with the two extended case reports … see paragraphs 37 - 44) 9. It may be possible for a candidate to obtain additional experience in radiological interpretation by reading radiographs provided from a film library by their adviser. This would benefit all candidates, but would be of particular benefit to any candidate whose personal caseload was lower than that specified in paragraph 2a above. It is recommended that candidates consider organising this on a regular basis throughout their period of study. 10. Candidates should also be prepared to consider any other reasonable proposal for gaining additional experience to compensate for shortfalls e.g. spending a short period gaining intensive experience of radiology at a Veterinary School. Small animal caseload 11. As the emphasis of the Certificate is on small animal experience, candidates working in an Approved Practice which is devoted primarily to equine and/or farm animal work would be expected to obtain at least 60 days experience doing small animal radiography/radiology during their period of enrolment. Large animal caseload 12. At least 10% of cases should involve horses or farm animals. Predominantly small animal practices will not have a sufficiently high workload in large animals and candidates must arrange to spend time at other centres gaining experience with species not dealt with in sufficient numbers in their own practices. 13. If a candidate has no exposure to equine/large animal work in his or her Approved Practice, then the minimum period of time needed to gain the necessary experience will be six working days 2 per year, spent in a centre where it is expected that several horses/large animals would be radiographed daily. Enrolment 14. Candidates may apply for enrolment and approval by the Board of the proposed period of experience in October of any year. The annual closing date for enrolment is 1 November. 15. Candidates must ensure that details of the veterinary practice at which they intend to gain their experience are stated on the application form. 16. For candidates following the “approved practice” route, the minimum two-year period during which experience will be gained should begin on 1 September of the enrolment year, two months prior to the annual closing date for enrolment. Candidates may begin entering cases into their case log (see paragraphs 31-33, Annex A & B) from this date. Change of place of work 17. If a candidate changes his/her place of work a new E1(a) form must be submitted, within 2 months' of the date of the change. The Board will consider the application as soon as possible after receipt and the Secretary will write to confirm that the practice has been approved for the purposes of gaining experience for the examination. For Candidates Applying for Final Approval of Experience in 2008/2009 (Approved Practice route) 18. It has been agreed to introduce case logs at the point when candidates apply for Final Approval of experience in the November before the examination, as evidence of their experience in radiography. The submitted work requirements for the examination in 2007 and beyond have also been amended as set out in paragraph 31 onwards, and will require candidates to produce reports on cases listed in their case log, with the RCVS Board selecting some of the cases for the candidate to write up. 19. Candidates will need to submit a case log at the time of applying for Final Approval demonstrating their imaging experience over at least the previous two years. The case log should contain 500 cases. The candidate should be responsible for the radiography of these cases, and the selection should demonstrate that the caseload was spread throughout the period that approval of experience is being sought. If candidates have not reached 500 cases in their case logs by the time of applying for Final Approval, they should continue to enter cases until 500 cases have been reached, and delay applying for Final Approval until the following year. APPROVED CENTRE ROUTE Approved Centres for Veterinary Diagnostic Imaging 20. Veterinary surgeons undergoing a full-time diagnostic imaging residency-type programme at an Approved Centre may enter the Certificate examination via the Approved Centre route. 3 Specific Experience 21. Before applying for Final Approval to sit the examinations, “approved centre” candidates must have spent a period of time gaining experience, which must be approved by the Board. The minimum time gaining this experience is two months in a full-time diagnostic imaging residencytype programme at one of the approved centres listed in paragraph 21. 22. Candidates following the Approved Centre route will not be permitted to apply for Final Approval until they have been Members of the College or held an approved veterinary qualification for at least two years. 23. Candidates who are involved in diagnostic imaging on a full-time basis will be allowed to prepare for, and sit the Certificate examinations in one year. Candidates who are working in an Approved Centre but not in diagnostic imaging on a full-time basis, in another clinical area, or studying for another qualification at the same time as preparing for the Certificate, will not be allowed to prepare for and sit the Certificate examinations in one year and should follow the guidelines for the Approved Practice route. Enrolment 24. Candidates may apply for enrolment and final approval of experience by the Board of the proposed period of experience in September of any year. The annual closing date for enrolment is 1 November. 25. Candidates must ensure that details of the Approved Centre at which they intend to gain their experience are stated on the application form. 26. The minimum two-month period during which initial experience will be gained should begin on 1 September of the enrolment year, two months prior to the annual closing date for enrolment. Candidates may begin entering cases into their case log (see paragraphs 31-33, Annex A & B) from this date. Change of place of work 27. It is expected that the caseload seen in this two months is representative of the caseload that will be seen by the candidate between applying for Final Approval and the end of the Certificate examinations. If a candidate does not continue to be involved in diagnostic imaging on a full-time basis at their Approved Centre after they have been accepted for Final Approval, they must inform the RCVS of this change by submitting a new E1(a) form within two months. The Board shall then decide if it is suitable for this candidate to continue with the examination in that year or whether further experience will be required to complete the examination. For Candidates Applying for Final Approval of Experience in 2008/2009 (Approved Centre route) 28. It has been agreed to introduce case logs at the point when candidates apply for Final Approval of experience in the November before the examination, as evidence of their experience in radiography. The submitted work requirements for the examination in 2007 and 4 beyond have also been amended as set out in paragraph 31 onwards, and will require candidates to produce reports on cases listed in their case log, with the RCVS Board selecting some of the cases for the candidate to write up. 29. If a candidate fulfils the requirements for enrolling via the Approved Centre route, they will be allowed to prepare for, and sit the Certificate examinations in one year. Candidates will be permitted to submit a provisional case log containing a minimum of 150 cases (dated from 1 September) with their application for Final Approval. A second completed case log (containing this initial minimum of 150 cases plus a further number to reach a total of 500 cases) would then need to be submitted to the RCVS Board Secretary in hard copy or email by the 1 July before the date of the written stage of the examination, otherwise they will not be permitted to enter this stage of the examination. The candidate should be responsible for the radiography of these cases, and the selection should demonstrate that the caseload was spread throughout the period that approval of experience is being sought. GUIDANCE ON COMPILING A CASE LOG 30. The case log is a log of the imaging cases whose radiography the candidate is responsible for. 31. All imaging cases undertaken by the candidate should be listed with case numbers and/or other identifying details from the date of introduction of this new system. The case log provides evidence that the required caseload (radiographic and ultrasonographic, including special techniques) has been seen. Further guidance on compiling case logs is attached to these notes (Annex A and B). 32. ALL SUBMITTED WORK, i.e. Case logs and Case Reports should be anonymous and will be treated in confidence by the Board Members and Examiners. THE EXAMINATION 33. The examination will consist of three sections: (a) Ten short case reports of 500 words each, including large and small animals, selected by the Diagnostic Imaging Board¥ , and two extended case reports of 2,500 words each, selected by the candidate. (b) TWO x 2 hour written papers, and (c) an oral and practical examination. ¥ The exception is candidates who received final approval of their experience before 1st November 2005, who will continue to choose their own cases. However, it is recommended that such candidates contact RCVS for a clear indication of how they are affected by the transition to the new format. Format 34. The submitted work requirements from 2006 onwards consist of radiographs, together with reports of the required number of cases (see above) for which the candidate has been responsible. In contrast to previous regulations, these cases will be chosen by the Board from the candidate’s case log after it has been submitted. 5 35. The examiners expect to see a variety of cases, and therefore will expect to be provided with a log book which includes a series which spans the breadth of body regions. 10 SHORT CASE REPORTS (500 WORDS EACH) 36. The reports should focus on the reason for the study, the candidate’s assessment of its justification and its quality, the important imaging features and the diagnosis. Five of the Ten cases will be chosen by RCVS to include special radiographic projections, contrast techniques and/or ultrasonography, and Five will be chosen to look at a full range of conventional plain film radiographic studies. They should be accompanied by the original films or good quality copies. 37. The emphasis for this new-style case report has changed slightly from the previous format. The examiners are looking for evidence of familiarity with a range of radiographic techniques and the ability to use these techniques in practice. 38. Reports must be typewritten and follow the format outlined below: a. Patient identification; species, breed, age and sex b. The reason for the study, i.e. a very brief account of the relevant history and clinical signs c. Radiographic appraisal: positioning, exposure, processing, safety factors, etc. d. Radiological report e. Diagnosis or differential diagnosis with brief justification for ranking Failure to follow this format or to submit the summary sheet will result in deduction of marks. 39. All films relevant to a case should be submitted. On some occasions this may necessitate the inclusion of films on which the candidate believes there are no abnormalities, but it must be borne in mind that submission of too many films reflects poor case selection. Although it is recommended that original films only should be used in these case reports, if copy films are submitted as part of a case, these should be of diagnostic quality. No credit can be given for lesions which are evident on original films but absent from copies. The use of poor quality copy films is to be discouraged and will result in marks being deducted. 40. The examiners will award a small proportion of marks for presentation. 41. The candidate must be responsible for the radiography of all of the cases in the case log. This means that the candidate’s role must be made very clear in the log book. Any lay assistance should be minimal and should be recorded. TWO EXTENDED CASE REPORTS (2,500 WORDS EACH) 42a. The two extended case reports should be selected by the candidate from cases that they have handled, to deal with contrasting areas, for example a small animal abdominal problem and an equine foot problem. They should be “editor-ready” (publishable quality), with the candidate 6 indicating the Journal “instructions to authors” which have been followed, but do not necessarily need to be original and worthy of publication on that score. However, diagnostic imaging should have played the major part in the ultimate resolution of the case. Assessment will focus on written communication skills, accuracy of radiological interpretation and integration of all information on the case into a satisfactory conclusion. They should include images, which may be scanned in to complete the appearance of the manuscript. However, the original radiographs must also be sent to aid the Examiners. 42b. 43. Examples of the style that would be suitable for submission as an extended case report include: • Dunn, M.E., Blond, L., Letard, D. and DiFruschia, R. (2007) Hypertrophic osteopathy associated with infective endocarditis in an adult boxer dog. Journal of Small Animal Practice, 48, 99-103 • Kirkby, K.A., Bright, R.M. and Owen, H.D. (2005) Paraoesophageal hiatal hernia and megaoesophagus in a three-week old Alaskan malamute. Journal of Small Animal Practice, 46, 402-405 • Seco Diaz, O., Reef, V.B., Martin Jr, B.B., Ross, M.W. and del Piero, F. (2003) Rupture of the biceps tendon of a Thoroughbred steeplechase horse. Equine Veterinary Journal, 35, 110-112 • Jenner, F., Solano, M., Gliatto, J., Lavallee, S. and Kirker-Head, C. (2003) Osteosarcoma of the tarsus in a horse. Equine Veterinary Journal, 35, 214-216 Candidates are asked to submit two electronic versions of their submitted work (short and long reports) together with their hard copy. One copy will be sent to the examiners, and the other electronic version will be retained at RCVS for purposes such as checking the word count. The electronic versions should be Microsoft Office 2000 or XP compatible and should be submitted on CD. Please ensure that the disks are easily identifiable by placing them in an envelope with your name, candidate number and ‘Electronic version of submitted work for Certificate in Veterinary Diagnostic Imaging’ marked clearly on the front of the envelope. The CD should be labelled with the candidate number only. INSTRUCTIONS FOR SUBMISSION AND RESUBMISSION OF CASEBOOKS 44. All candidates who are eligible and wish to enter for the examination will be issued with an individual examination number, together with the list of cases to be submitted, when they receive their entry forms in the December prior to the examination. If there are any problems with this list, the candidates should contact the RCVS as soon as possible. 45. This candidate number is the only identification which should appear on case reports submitted for examination. It must be clearly marked in large letters on the outer packaging of the case reports which must be submitted to the RCVS, for the attention of the VDI Board Secretary, before 1 March of the year of examination 46. Candidates who are re-sitting the examination must also submit their case reports to the RCVS before 1 March and must indicate whether the case reports are unchanged or have been updated. 7 47. The case reports are sent from the RCVS to the examiners without being unpacked but must be in a container which is suitable for carrying. A strong art portfolio with a handle is recommended. 48. The radiographs of each case together with the report of the case must be presented in a separate envelope. The envelopes must be numbered sequentially and the numbering used on the summary sheet must correspond. 49. Where a case has more than one radiograph, each should be numbered clearly to correlate with reference numbers in the report. 50. A summary sheet must be submitted with the radiographs and case reports. A blank summary sheet is attached to these notes (Annex C). 51. The Board has prepared a sample of a good casebook/bad casebook for information. Please see (Annex D). GRADING SCHEME: 52. The submitted work will be graded “Good Pass”; “Pass” or “Fail”. 53. Certificate work that achieves a “Good Pass” may be used as a sample for prospective candidates. WRITTEN EXAMINATION: 54. Candidates are warned that answers should be given specifically and that illegible handwriting may result in examiners being unable to award marks for information which candidates intended to convey. Format 55. There will be two x 2-hour written papers: Paper l: 10 x 12 minutes questions on radiological physics, radiation protection and techniques. Paper2: 5 x 30 minute essay questions on radiographic anatomy and radiological interpretation of which 4 must be answered. Marks Scheme: 56. Paper l will be marked out of 50 marks Paper ll will be marked out of 50 marks Total Mark for this Section (b) = 100 marks 8 PRACTICAL AND ORAL EXAMINATION: Format 57. Practical: This lasts 3 hours and consists of 15 stations all of which deal with interpretation. At least 12 stations will consist of a series of films from a single case. The remainder will test appreciation of themed radiological features. 58. Candidates are expected to interpret radiographs of a series of cases without access to clinical information. 59. Candidates should not comment on radiographic quality at length unless it detracts from film interpretation. 60. Twelve minutes per set of films are allowed. 61. Candidates will be required to satisfy the examiners that they have reached an acceptable standard in both large and small animal cases. A number of the questions may relate to large animals. Candidates should not rely solely on the large animal course for large animal film interpretation skills. 62. Oral examination: This lasts approximately 30 minutes, and candidates are expected to discuss radiological physics and techniques and to demonstrate their verbal skill in radiological interpretation. They may also be questioned on their case reports. Marks Scheme 63. The Practical will be marked out of 75 marks The Oral will be marked out of 25 marks TOTAL Mark for this Section (c) = 100 marks [Candidates must achieve 50% in each part]. SYLLABUS AND READING LIST: Ultrasound Examinations 64. The 1998 revision to the syllabus introduced the requirement for some practical experience of ultrasound as well as theoretical knowledge. 65. The Board has deliberately not defined a recommended caseload for ultrasound examinations at this stage. 66. The E1(a) application form includes questions about equipment, caseload and a candidate’s plans for gaining additional experience. Candidates are asked to report this information to the Board by completing these sections of the application form. They are advised to discuss any queries about the need for additional experience with their advisers who will be able to advise 9 depending on the number and range of ultrasound examinations carried out at the candidate’s own place of work. 67. With increased access to the internet, and easy availability of on-line literature searches, the Board decided to ‘freeze’ the reading lists in 2002. Candidates are expected to do their own research and will be encouraged to seek advice on suitable reading matter from their Advisers. ADVISERS: 68. Candidates are advised to look in the back of the RCVS Register of Members for the names of Certificate and Diploma holders of Veterinary Radiology and Veterinary Diagnostic Imaging and seek their agreement to act in this capacity, prior to enrolment. 69. Candidates in Veterinary Diagnostic Imaging are fortunate in having a large number of very experienced advisers whose advice they may seek. All candidates are strongly recommended to consult their advisers, especially in connection with preparing their case reports. 70. Before submitting their casebook for examination, candidates should arrange for their advisers to look at least three of their case reports. The candidate's case report declaration should indicate clearly the extent of the adviser's input and the declaration should be countersigned by the adviser. 71. The adviser is not permitted to examine each case in detail and no more than one case, which has received major input from an adviser, should be submitted for the examination. RADIATION PROTECTION ADVISER: 72. Form E1(a) requires candidates to give details of their Radiation Protection Adviser. (Please note the Radiation Protection Adviser is not the same person as the Radiation Protection Supervisor in your practice. The Practice’s Radiation Protection Adviser is an external expert who is either a medical physicist or a veterinary radiologist with experience and training in the area of radiation safety.) Particular care should be taken to complete this accurately. 73. When the RPA is not known to the Board, the candidate may be asked to provide a copy of his/her practice's local rules and the written system of work as defined in the 1999 Ionising Radiation Regulations, or the equivalent if experience is being gained outside the United Kingdom. ATTENDANCE AT SHORT COURSES: Radiological Physics 74. In previous years, candidates for the Certificate in Veterinary Radiology were required to attend a course in Radiological Physics before they could enter for the examination. This is no longer a specific requirement, but candidates should be aware that this subject will continue to be covered in the examination and they should ensure that they have prepared adequately. 10 Please note that the European Association of Veterinary Diagnostic Imaging (EAVDI) no longer run the annual physics course. Large Animal Radiography and Radiology 75. Candidates must attend a course in large animal radiography and radiology, unless they can show that they are able to obtain substantial working experience in their approved practice or centre (at least an average of 1 case/week). In this case, an application for exemption can be made on form E1(a). 76. Courses are run by the Royal Veterinary College and by BEVA, and the RCVS can arrange for enrolled candidates, who have not already attended a course, to receive details. 77. Candidates should contact the course organisers direct with any queries relating to booking places. Other Courses 78. Candidates are strongly recommended to attend any other courses in veterinary diagnostic imaging and radiology which may be available during the time they are preparing for the examination, e.g. those organised by the EAVDI, BSAVA, BEVA or individual veterinary schools. Such courses are generally widely advertised in the veterinary press but are often quickly over-subscribed. You are therefore advised to register early. MEMBERSHIP OF VETERINARY ASSOCIATIONS/SOCIETIES: 79. All candidates are advised to join the European Association of Veterinary Diagnostic Imaging (EAVDI). The British and Irish Division: Chairman: Panagiotis Mantis DVM DipECVDI ILTM MRCVS Queen Mother Hospital for Animals The Royal Veterinary College Hawkshead Lane North Mymms Hatfield, Hertfordshire AL9 7TA Tel: 01707 666286 Email: [email protected] Secretary: Nic Hayward BVM&S DVR DipECVDI MRCVS Great Western Referrals Unit 10, Country Park Business Park Shrivenham Road Swindon SN1 2NR Tel: 01793 603800 Email: [email protected] 11 European Association of Veterinary Diagnostic Imaging (EAVDI) Prize 80. The winner of the EAVDI prize for the best casebook will be asked to submit a copy to the RCVS Library and Information Service. Although the radiographs to which the case reports relate will not be held, the casebooks can be referred to as examples of expected style and format. ABBREVIATION OF QUALIFICATION: 81. Holders of the Certificate in Veterinary Diagnostic Imaging are permitted to use the abbreviation “CertVDI” after their names. Revised: November 2002, February 2003 (name change from Veterinary Radiology to Veterinary Diagnostic Imaging) March 2004, April 2005, April 2006, April 2007, April 2008. 12 Annex A GUIDELINES FOR COMPLETION OF THE VETERINARY DIAGNOSTIC IMAGING CASE LOG (REQUIRED WHEN APPLYING FOR FINAL APPROVAL OF EXPERIENCE) 1. Candidates must adhere to the size (A4) and page format provided for the Case Log and should complete an entry for each of the following headings (see sample layout). The cases should be arranged and numbered sequentially, allowing for easy identification of the animal during progression of its treatment. 2. The case logs must be comb bound or a similar slim binding method employed. A lack of binding or the use of a lever arch file is not acceptable. 3. Currently, this certificate is aimed at veterinary surgeons in private practice or at a veterinary school at which 500 or more cases are radiographed per annum, and where the candidate is responsible for radiographing at least 250 of those cases. All cases where the veterinary surgeon was responsible for the radiography should be included in the case log. 4. Information required in the case log should include a means for identification and retrieval (case number, practice reference, date, breed, age & sex), clinical signs, region(s) radiographed, radiographic views taken, notation to identify those cases in which special imaging studies were taken (eg ultrasound, contrast procedures, oblique views), and diagnosis. CASE NO, PRACTICE REFERENCE, DATE, BREED, AGE, SEX, 5. A consistent format to enable the subsequent identification of the patients should be used and as stated earlier these should be arranged sequentially. It is understood that different practices have different means of identification for filing of radiographs. That method of identification should be included for ease of retrieval of cases when the Board has decided which radiographs shall be used for the case reports. Examples may include use of the Surname, or use of the patient’s hospital reference number, or an individual case reference number. CLINICAL SIGNS 6. The most important features of the clinical presentation should be included here: e.g.: ‘a dog with a grade 3/6 left sided cardiac murmur, with reduced exercise tolerance, increased respiratory effort and a cough’ could be written as ‘cardiac murmur, exercise intolerance, cough’. PROCEDURE 7. The region(s) radiographed should be listed, including the radiographic views taken of those regions. Where other imaging procedures are used (eg abdominal ultrasound, echocardiography, retrograde urethrogram, intravenous urography, stressed views of the carpus) 13 DIAGNOSIS 8. The radiographic diagnosis of the problem should be included. It is accepted that there may be normal imaging findings and a definitive diagnosis may be made through other means (eg surgical biopsy, necropsy). In these instances, the definitive diagnosis should also be included. In those cases where imaging findings are normal, and no further means of diagnosis were undertaken, then the diagnosis should be listed as ‘open’. 9. Candidates are warned that Case Logs that do not adhere to the above guidelines will be rejected. Similarly, Case Logs that arrive at the Royal College after the closing date of 1st November will not be accepted, and the candidate will be unable to proceed to the next year’s examination. Candidates should ensure that they retain a copy of their case log so that they can take it to the clinical/oral/practical examination. 14 Annex B 1.

(Regurgitation of a textbook list which has not been “individualised” to the case is one of the worst faults at this level.) • Positioning and/or processing faults unrecognised and therefore uncorrected across the casebook. “GOOD CASEBOOK” • • • • • “Keep it simple”. An adequate series of radiographs to assess the region of interest Radiographs well positioned, well centred, good exposures, attention to processing Lungs appropriately inflated on radiographs Criticism of any film where this is appropriate. However repeated instances of poor radiography, although adequately criticised, would not be considered appropriate for a “good casebook”, as it would be expected that these errors should have been corrected by the candidate as they gained experience. • Use of appropriate radiological terminology when describing changes seen. • A differential diagnoses list that is appropriate to that particular case, and not a random regurgitation of a “textbook” list. • A justification of the differential diagnoses list that is brief and pertinent to that case. 17 ADVICE FOR TWO EXTENDED CASE REPORTS The recommendations listed in the Advice for Short Answer Case Reports should be followed for the Two Extended Case Reports as well. However, two further points need to be made: • Many candidates have problems with difficult or rare conditions that may need complicated investigations, which results in inappropriate studies that are poorly described and poorly presented. Choosing a complex case and writing an unsatisfactory report will result in marks being lost. Remember that these cases do not necessarily need to be original or worthy of publication but should be of publishable quality (i.e. “editor-ready”) • Diagnostic imaging should have played a major part in the ultimate resolution of the case. Assessment of the two extended case reports will focus on written communication skills, accuracy of radiological interpretation, and integration of all information on the case into a satisfactory conclusion. Candidates should recognise the level of information provided by the radiographs, such as whether these were pathognomonic or how the pattern of changes narrowed down the possible diagnoses to allow the history and/or the clinical examination to resolve the issue. Discussion of the case could also include why this case was of interest, why the changes were typical or atypical, and what other imaging modalities may be of benefit. Mention of relevant imaging references that were helpful should also be included. 18 C THE ROYAL COLLEGE OF VETERINARY SURGEONS CERTIFICATE IN VETERINARY DIAGNOSTIC IMAGING February 2003 (name change from Veterinary Radiology to Veterinary Diagnostic Imaging) Syllabus and commentary A.

They should understand the principles of fluoroscopy with image intensification and Doppler ultrasonography including colour flow and the types of conditions in which these techniques may be usefully employed. Species The scope of the examination is related to those conditions likely to be encountered in general veterinary practice. Therefore the above outline is concerned primarily with conditions met in small animal practice. Candidates will, however, be expected to appreciate the value and limitations of the use of low power X-ray apparatus in the investigation of other species and to be able to recognise the conditions which are commonly demonstrated by the use of such machines. Radiation protection Candidates should be familiar with the "Guidance notes for the protection of persons against ionising radiations arising from veterinary use". It is essential that they show not only theoretical knowledge of these Notes but also evidence of the practical application of the Regulations i.e. in their submitted radiographs and written reports. 21 THE ROYAL COLLEGE OF VETERINARY SURGEONS D Specialisation and Further Education CERTIFICATE IN VETERINARY DIAGNOSTIC IMAGING February 2003 (name change from Veterinary Radiology to Veterinary Diagnostic Imaging) READING LIST Candidates should note that the reading list for Veterinary Diagnostic Imaging was frozen in 2002 and will eventually be withdrawn.
