A patient receives 285uCi of I-123 NaI orally for a thyroid uptake study. Calculate the 24
hour percent uptake using the given data:
Dose Count= 1425916 cpm
Background= 88 cpm
Patient counts= 193046 cpm
The image was obtained while performing a WBB scan on a 62 year old male, the most
probable reason for the appearance on the image is:
a. metastatic disease
b. trauma to chest wall
c. localized osteoporosis
d. osteomyelitis
e. Paget's disease - CORRECT ANSWER✔✔- B. Trauma to chest wall
(metastatic will appear sporadically, pagets will show increase brain, femur, and pelvis.
Trauma is usually displayed as a pattern)
,You are receiving a completed MPI pharmacologic study which of the following descriptions
suggest that the patient has a myocardial infarction?
a. abnormal resting Tc99m tetrofosmin, normal stress Tc99m tetrofosmin
b. abnormal resting MIBI, normal stress Tl-201 Thallium Cl
c. normal resting Tc MIBI, normal stress Tl201
d. abnormal resting Tl201, abnormal stress Tc MIBI
e. Abnormal stress Tl201, normal redistribution Tl201 - CORRECT ANSWER✔✔- D. Both
resting and stress will appear abnormal to indicate an infarction
Which electron transition process involves monochromatic incident X-ray yeilding a photon
and other electron's conservation of energy by moving shells? - CORRECT ANSWER✔✔-
Characteristic X Ray Production
How many dpm will yield a count rate of 640 cpm when measured by a detector with a
counting efficiency of 85%? - CORRECT ANSWER✔✔- 753 dpm
E=C/A
A= 640cpm/0.85 =753
E=cpm/dpm
Proper patient transfer technique includes all of the following except:
a. letting the patient help as much as possible
b. maintaining a wide base of support
c. having the patient's center of gravity away from your COG
d. using muscles of the arms and legs for lifting
e. getting help when it is needed - CORRECT ANSWER✔✔- C. Center of gravity should be
close together
prior to performing an oncology PET/CT scan, the patient height and weight is recorded in
order to assist in the circulation of
a. CTDI
b. EF
c. CO
, d. SUV
e. CTAC - CORRECT ANSWER✔✔- D. standard uptake value
If tracer concentration is visualized in the skeleton, kidneys, and liver on a WBB scan the
most likely explanation for these findings is that:
a. imaging was performed too soon following tracer admin
b. the radiopharm contained excess free Tc
c. the patients renal function is compromised
d. the incorrect radiopharm was administered
e. there is excess alumina in the generator eluate - CORRECT ANSWER✔✔- e. excess
alumina will cause hydrolyzed reduced Tc build up in the elution and cause artifacts on WBB
images
Which of the following image findings is most consistent with chromatography results of a
Tc SC kit demonstrating 90% radiopharm purity?
a. thyroid uptake
b. bone uptake
c. lung uptake
d. gallbladder activity
c. kidney uptake - CORRECT ANSWER✔✔- A. thyroid uptake, 92% is the radiopharm
purity required for SC kits and free Tc will localize in the thyroid naturally
The results shown below were obtained when the Tc99m eluate was assayed for Mo99
breakthrough at 0600, immediately following elution
Mo99 10uCi
Tc99m 416mCi
which of the following statements is true about this elution at 1700?
a. The eluate should not be used to label compounds with Tc99m
b. The eluate does not contain sufficient Tc99m activity
c. The eluate may be used to label compounds with Tc99m
d. The eluate must not be administered to patients
