PET/CT EXAM PREP (BRAND NEW!!)
The initial diagnosis of melanoma is established by:
(A) PET examination
(B) CT examination
(C) Histologic evaluation
(D) Dermatologist evaluation - Correct Answer - (C) Histologic
evaluation
Which of the following is cyclotron produced positron-emitting
radionuclide?
(A) Copper-62
(B) Nitrogen-13

(A) Apoptosis
(B) Mutation
(C) Proliferation
pg. 1
,2|Page
(D) Metabolism - Correct Answer - (C) Proliferation
What is the percent error of the dose calibrator reading if a 4 ml
reference volume (expected) of the geometry test reads 2.8 mCi, and the
actual reading obtained in 10 ml volume is 2.5 mCi?
(A) 12%
(B) 10.7%
(C) −10.7%
(D) −12 % - Correct Answer - (B) 10.7%
The given volume is additional information and must be disregarded,
since the percent error formula does not utilize it.

in the axial center of the gantry
Primary applications of PET and PET/CT in the brain imaging include
all of the following EXCEPT:
(A) Differentiation of dementias
(B) Evaluation of primary brain tumors
(C) Evaluation of brain injuries
