If a patient receives 99mTc-MAA while in an upright position, which of the
following statements most likely represents what will be seen on the perfusion
lung images.
A. Increased tracer activity in the lung apices
B. Decreased tracer activity throughout both lungs
C. Decrease tracer activity in the lung bases
D. Decrease tracer activity in the lung apices - Correct Answer-D. Decrease tracer
activity in the lung apices
Technetium 99mTc-MAA should be injected during quiet respiration, with the
patient supine to minimize the normal perfusion gradient between the apex and
the lung base. (When the patient is supine, the effect of gravity, which hinders
blood flow to the lung apices, is minimized, allowing uniform tracer distribution
throughout the lung.)
In case of a radioactive spill that involves contamination and life-threatening
injuries to personnel, which of the following actions should be given priority?

, Nuclear Medicine: Exit Exam Practice Exam Prep
A. Confinement of the radioactive spill
B. Decontamination of the victim
C. Notification of the radiation safety officer
D. Medical treatment of the seriously injured - Correct Answer-D. Medical
treatment of the seriously injured
Medical treatment for life-threatening conditions always takes precedence over
any other activity. To prevent the spread of contamination, the victim can be
wrapped in a sheet for transport to the treatment area.
A vial of 67Ga-citrate is calibrated to contain 5 mCi at 0600, Pacific Standard Time
on March 8th. How much activity does the vial contain on March 9th at 1200,
Eastern Standard Time?
A. 3.7 mCi
B. 3.9 mCi
C. 4.9 mCi
D. 6.3 mCi - Correct Answer-B. 3.9 mCi
The easiest approach is to first equate the calibration time to EST. There's a 3-hour
time difference between Pacific Standard Time and Eastern Standard Time, so
0600-PST = 0900 EST.Once this is performed the problem is a straightforward
decay correction problem. The elapsed time between 0900 EST on March 8th and
1200 EST on March 9th is 27 hours. From a decay factor table for Ga-67, the decay
factor for 27 hours is 0.787 the total activity is decay corrected for 27 hours to
determine the total activity at 1200 EST on March 9th.

Ga-67 has a (Tp ½ =78 hrs)
A(t)-A(0) X D= 5 mCi X 0.787= 3.9 mCi
According to the NRC regulations, which of the following signs should be posted in
unrestricted areas?
A. Caution: Radiation Area
B. Authorized Personnel Only
C. Caution: Radioactive Materials
D. No posting is required - Correct Answer-D. No posting is required
Unrestricted area is an area in which an individual could receive from an external
source a maximum dose of 2 mrem (20 uSv)/h, and access to the area is neither
limited nor controlled by the licensee.
SPECT brain Imaging may begin how soon after the administration of 99mTc-
exametazime?
A. Immediately
B. 15-20 minutes
C. 1-2 hours
D. 24 hours - Correct Answer-C. 1-2 hours

Injection-to-Imaging time for SPECT brain Imaging is 90 minutes or later
Which of the following is the initial positioning for visualizing gastrointestinal
bleeding with labeled red blood cells?
A. Lower esophagus at the top of the field of view
B. Xiphoid in the middle of the field of view
C. Lower border of the liver and spleen at the top of the field of view
D. Symphysis pubis in the middle of the field of view - Correct Answer-C. Lower
border of the liver and spleen at the top of the field of view
Place the patient supine under the camera to include the inferior margin of the
liver at the top of the field of view
A patient with a chest tube arrives in the nuclear medicine department for an
Imaging study. The technologist should:
A. Cancel the procedure because the chest tube apparatus will interfere with the
study
B. Place the chest tubes external apparatus on the Imaging table next to the
patient
