The image depicts an anterior view of the rib cage and proximal
upper extremities. The acromion processes would be
demonstrated on a posterior view of the upper thorax that
includes the scapulae.
Which of the following is common to imaging gastroesophageal
reflux in both adults and children?
A. The patient ingests diluted hydrochloric acid with the
radiopharmaceutical
B. 99mtc sulfur colloid is the radiopharmaceutical of choice
C. The patient must fast from Midnight before the test
D. An abdominal binder is used to increase pressure over the
abdomen - THE CORRECT ANSWER-B. 99mtc sulfur colloid is the
radiopharmaceutical of choice
99mTc-Sulfur Colloid is the radiopharmaceutical used to image
gastroesophageal reflux in both adults and children. However,
adults are administered a mixture of dilute hydrochloric acid,
orange juice and tracer after fasting from midnight. In infants
and toddlers, the procedure is performed at the time of a
scheduled feeding, so they may fast as little as two hours before
,receiving the tracer. In adults, an abdominal binder is used to
increase external abdominal pressure to demonstrate more
subtle instances of reflux. Because the abdominal muscles are
important in pediatric respiration, the binder is typically not
used with children, particularly infants.
The shelf life of most 99mTc-labeled radiopharmaceuticals is:
A. 4-6 hrs
B. 6-8 hrs
C. 10-12 hrs
D. 16-18 hrs - THE CORRECT ANSWER-B. 6-8hrs
For most 99mTc-Radiopharmaceuticals, the expiration time is
6 hrs, equal to the physical half-life of 99mTC (t1/2= 6 hrs)
On an intrinsic field uniformity image, the area of increased
activity around the image is called:
A. Flare phenomenon
B. Septal penetration
C. Edge packing
D. Halo effect - THE CORRECT ANSWER-C. Edge packing
The phenomenon known as Edge packing can show up as a
bright rim of activity around the perimeter of the [intrinsic
flood]. To prevent Edge packing, most manufacturers provide a
lead- shielded ring that masks the effect when attached to the
edge of the camera head.
,A patient who becomes hypoglycemic may exhibit all the
following signs and symptoms except:
A. Weakness and shakiness
B. Irritability
C. Nausea and vomiting
D. Confusion - THE CORRECT ANSWER-C. Nausea and vomiting
The onset of symptoms of hypoglycemia may be sudden and
include general weakness, sweating, clammy, cold skin,
tremors, nervousness, irritability, hunger, blurred vision and
loss of consciousness. The condition can be remedied quickly
with the administration of sugar (3 pieces of candy or fruit
juice)
Which of the following is the correct patient/camera
positioning for imaging a transplanted kidney?
Patient position Camera positions
I Upright Anterior
II Upright Posterior
III Supine Anterior
IV Supine Posterior
A. I
B. II
C. III
, D. IV - THE CORRECT ANSWER-C. III
Imaging of renal transplants is performed with the patient
supine. Anterior images are obtained over the iliac fossa
containing the transplanted kidney.
The gamma ray spectrum shown below was obtained at a
voltage of 800. To move the photo peak into the window, which
of the following actions should be taken?
A. The voltage should be increased
B. The voltage should be decreased
C. The window should be widened
D. The window should be moved - THE CORRECT ANSWER-A. The
voltage should be increased
As voltage is increased, the gamma-ray spectrum moves to the
right. Therefore, increasing the voltage will shift the photopeak
toward the window and, if the voltage is increased sufficiently,
into the window.
Which of the following 99mTc-labeled agents is the preferred
radiopharmaceutical for demonstrating intermittent
gastrointestinal bleeding?
A. Human serum albumin
