7. Materials of methodical maintenance of employment on the topic number 1 "Physical and technical bases of radiological methods of investigation (X-ray, Xray, tomography, kserorentgenografiya, bronchography et al.). Formation of Xray diagnostic imaging". 7.1. The tests for the class: 1. On fluorogram Image: 1. positively; 2. negative; * 3. inverted; 4. there is no right answer. 2. What method of beam diagnostics using ionizing radiation: 1. MRI 2. CT * 3. SPL 4. thermography. 3.Naimenshimi have side effects: 1. Any modern ionic contrast agent; 2. nonionic contrast media; * 3. Water-soluble contrast agents; 4. fat-soluble contrast agents, especially when administered intravenously. 4. On the X-ray image of the screen: 1. positive; * 2. negative; 3. inverted; 4. there is no right answer. 5.Usilitel X-ray image (URI): 1. improves the quality of the resolution of the X-ray * 2. It can reduce the cost of research 3. increases the total radiation exposure 4. improves the quality of the resolution of the X-ray * 6.Protivopokazaniya for MRI: 1. uncontrolled hyperkinesis; 2. early pregnancy; 3. pacemakers; * 4. radiation sickness. 7.K nonionic contrast media include: 1. ultravist; 2. omnipak; * 3. triombrast; 4. bilignost. 8. As of the properties of the X-ray shows the ability of X-ray screen shine under their influence? 1. photochemical; 2. luminescence; * 3. penetration; 4. reflection; 5. Rentgenooptichesky 9.Izobrazhenie obtained using X-rays: 1. more than the size of the subject: * 2. less of the subject; 3. equal to your subject; 4. all answers are correct. 10.Istochnikom electrons to produce X-ray tube is used: 1. rotating anode; 2. cathode filament; * 3. a radioactive isotope; 4. the potential difference between the cathode and the anode. 11.For artificial contrast in radiology apply: 1. barium sulfate; 2. Organic iodine compounds; 3. gases (oxygen, nitrous oxide, carbon dioxide); 4. all of the above.* 12. As a shadow in the lung called macrofocal size? 1. about 5-6 cm in diameter; 2. segmental shadow; 3. 1.0-1.5 cm in diameter; * 4. 3-4 cm in diameter. 13.Do not are electromagnetic: 1. infrared rays; 2. sound waves; * 3. radio; 4. X-rays. 14. How is called a physical effect occurring at the cathode during operation of the X-ray tube? 1. thermionic emission; * 2. inhibition electrons with heat and X-rays: 3. electromagnetic induction; 4. characteristic radiation. 15. In the emulsion composition comprises: 1. Silver nitrate crystals and fluorescent; 2. silver bromide and silver iodide; * 3. silver fluoride; 4. fluorescent crystals. REFERENCE the responses to the tests preparatory phase of exercises number 1. 1. 2. 3. 4. 5. - 2 - negative; - 2 - CT; - 2 - non-ionic contrast agent; - 1-positive; - 1 - allows you to improve the quality, the resolution of X-ray; 4 - Improves the quality of the resolution of the X-ray; 6. - 3 - the presence of a pacemaker; 7. - 2 - omnipak; 8. - 2 - luminescence; 9. - 1 - more than the size of the subject; 10. - 2 - thread cathode filament; 11. - 4 - all of the above. 12. - 3 - 1.0-1.5 cm in diameter; 13. - 2 - sound waves; 14. - 1 - thermionic emission; 15. - 2 - the silver bromide and silver iodide; 50-60% correct answers - the test is considered valid, and the student gets 1 point for the credit-module system. Objective 1 A patient suspected of having the right lung is produced radiographic picture of the chest diseases. Question: On what is the principle of obtaining images on X-ray film? Answer: On the particular tissue differently to detain x-rays. Objective 2 The patient, long-suffering from cardiovascular disease, there is a pacemaker. On radiographs of OGC in the right lung is determined abnormal shadow with irregular contours. To clarify the diagnosis the doctor recommended to do a CT or MRI. Which diagnostic method can be used in this particular case? Answer: MRI. Objective 3 Patient pain on an empty stomach in the stomach. The doctor recommended to confirm the diagnosis X-rays and produce esophagogastroscopy stomach. With the passage through the small intestine. What a contrast agent should be used for X-ray of the stomach? Answer: Barium sulphate.
