Clinical Portfolio
• The Clinical Portfolio consists of the following
components:
– (1) Clinical Experience Documentation and Clinical
Competence Assessments
– (2) Professional Activities and Accomplishments
Record
– (3) Case Studies
– (4) Summative Evaluation Rating Scales.
Form CR-1: Summary of Clinical Experience and
Competence Assessments
• 1. This form is completed by the student as he or she: (a) completes
the requisite number of cases for the mandatory and elective
procedures; and (b) is evaluated by a radiologist on the mandatory
and elective procedures.
• 2. The student records the number of cases completed for each
mandatory and elective procedure he or she performs.
• 3. The student records only the date that the competency
assessment was completed. Note that the actual competence
assessments are completed by a radiologist using Form CR-2
• 4. The preceptor and program director must verify and sign the
bottom of Form CR-1. This form is submitted to ARRT at the time of
application.
Form CR-2: Clinical Competence
Assessments (Forms CR-2A through CR-2E)
• 1. These forms are completed by the radiologist at the time
he or she evaluates the student. There are separate
evaluation forms for each class of radiologic procedures:
– Form CR-2A: GI/Chest Form CR-2C: invasive nonvascular
– Form CR-2B: GU Form CR-2D: invasive vascular
– Form CR-2E: post-processing activities
• 2. The radiologist and student are required to sign the
bottom of Form CR-2 for each assessment, which is
subsequently reviewed and signed by the program director.
• 3. The student must submit a minimum total of 15
assessment forms to ARRT (12 mandatory and 3 elective
procedures).
Summative Evaluation
• The Summative Evaluation Rating Scales
address five skill areas:
– (1) evaluation of medical information
– (2) patient communication
– (3) radiation safety


77 year old female
No known surgery to gastrointestinal tract
No weight loss


Dysphagia
Pharyngeal perforation, aspiration, and fistula
were not clinically indicated therefore thick
and thin barium contrast was used and not
water soluble contrast.


The patient stated “food gets stuck in my
throat”
Other clinical reasons for performing an
esophagram include:






Dysphagia (difficulty swallowing)
Odynophagia (painful swallowing)
Globus (sensation of a lump in the throat)
Suspected aspiration
Postoperative assessment of laryngectomy
Penetrating Trauma

Endoscopy showed antral deformity follow up
with GI study recommended






Esophagram performed
Thick and thin barium used in vertical and
horizontal positions
Patient positioned upright in right lateral, AP,
and LPO
Patient positioned supine in RAO, AP and RPO
Images obtained of esophagus collapsed and
dilated with barium
Modifications of routine exam to image
visualized pathology

The chest x-ray shows
the Hiatal Hernia.
Notice the
circumscribed lucency
behind the heart.

Notice the small
Zenker’s
diverticulm.


Notice the distal
esophageal
diverticulum with
barium distending
distal esophagus
Image obtained in
upright position


Notice distal
esophageal
diverticulum has
barium pooling. In
comparison to
previous image there
are tertiary
contractions of the
distal tortuous
esophagus
Image obtained in
upright position
stomach


Notice the location of
the diaphragm, clearly
showing a Type IV
complex
paraesophageal hiatal
hernia.
Image obtained supine
notice difference in
appearance from prior
images done upright
showing or movement
of the hernia


Results:Multiple tertiary contractions of the esophagus
are seen associated with prominence of the
cricopharyngeus sphincter. 5mm in diameter Zenkers
diverticulum is noted. No aspiration or penetration is
seen. Large Hiatal hernia is seen with the majority of
the stomach herniated into the chest cavity. There is
considerable gastroesophageal reflux. A 2cm diameter
outpouching is noted of the distal aspect of the
esophagus compatible with distal esophageal
diverticulum.
Impression: Prominence of the cricopharyngeal
sphincter associated with small Zenkers diverticulum.
Significant motility dysfunction of the esophagus.
Diverticulum of the distal esophagus as described.
Large hiatal hernia. See above

The differentials for the hiatal hernia on the frontal
chest x-ray are:




retrocardiac lung abscess
retrocardiac empyema
epiphrenic esophageal diverticulum
There are no differentials for the esophagram images.
They could potentially be wrongly diagnosed.



The stomach could be wrongly diagnosed as a volvulus or
malrotation if the interpreter did not notice the level of the
diaphragm, but these diagnosis should be done on an UGI
where the duodenum is visualized
The zenckers diverticulum could be wrongly diagnosed as an
ulcer
The distal esophageal diverticulum could be wrongly
diagnosed as a large ulcer





Zenker’s diverticulum correlates with the sensation
of food getting stuck in the upper esophagus
Motility dysfunction which contributes to the
patient’s dysphagia.
Considerable gastroesophageal reflux (suspected
treatment or forgot to mention symptoms)
Asymptomatic distal esophageal diverticulum
Asymptomatic type IV complex paraesophageal
hiatal hernia






Treatment for the reflux would be recommended
such as Prilosec (an antacid).
Surgery of hiatal hernia only necessary if hernia
causes strangulation which cuts off the blood
supply or causes an obstruction
No treatment for asymptomatic type IV complex
paraesophageal hiatal hernia
No treatment for 77 year old asymptomatic distal
esophageal diverticulum
No treatment for the Zencker’s diverticulum
No treatment for dysmotility



Upper gastrointestinal barium study to
visualize the stomach and duodenum could be
done for further evaluation
Small bowel follow through with barium could
also be done to further evaluate potential areas
of obstruction.
CT with oral contrast of the abdomen and
pelvis could be performed to further evaluate
the anatomy
