NMTCB REVIEW TEST QUESTIONS AND ANSWERS
SET A+
✔✔a Mo/Tc generator has an elution efficiency of 89%. if 1.1 Ci of Tc is present on the
column, what is the estimated activity of eluate that will be obtained?
a. 97.9 Ci
b. 979 mCi
c. 979 uCi
d. 97.9 mCi - ✔✔b. 979 mCi
✔✔Tc DPTA has be used for all of the following, EXCEPT:
a. aerosol lung scanning
b. renal flow study
c. brain flow study
d. shunt patency
e. spleen scanning - ✔✔E. spleen scanning
✔✔which of the following is not used as an anticoagulant?
a. heparin
b. EDTA
c. ascorbic acid
d. ACD solution - ✔✔c. ascorbic acid
✔✔if the concentration of a solution desired is 2 mCi/ml and the 325 mCi of solute is
contained in a volume of 2.5 ml, how much water should be added to create the
solution?
a. 160 ml
b. 162.5 ml
c. 650 ml
d. 125 ml - ✔✔b. 162.5 ml
(Books says this, but pretty sure it's A-160 ml
, 2 mCi/ml = 325 mCi/x,
x= 162.5, but you already have 2.5 mL, so 162.5-2.5=160
✔✔the inferior wall of the heart is supplied by the:
a. LAD
b. LCX
c. RCA
d. LCA - ✔✔c. RCA
✔✔the uptake of FDG by tumors is based on:
a. a blood brain barrier breakdown (say that 5x)
b. the higher glycolytic rate of tumors relative to normal tissue
c. active transport
d. Antibody antigen reactions
e. receptor binding - ✔✔b. the higher glycolytic rate of tumors relative to normal tissue
✔✔In111 delivers a lower radiation dose to the patient than Ga67 because it only has
one gamma emission, whereas Ga67 has four.
a. true
b. false - ✔✔B. false
✔✔if dipyridamole is supplied in a 50ml vial containing 250 mg and a patient weighs
205 lb, how much volume will be needed from the vial to prepare his dose of 0.56
mg/kg?
a. 5.6
b. 10.4
c. 15.9
d. 22.6 - ✔✔b. 10.4
0.56 mg/kg x 93.2 kg= 52.2 mg / 5 mg/ml = 10.4 ml
✔✔if 450 mCi of TcO4 eluted from a generator contains 200 uCi Mo99, is the eluate
within the standards of radionuclidic purity set forth by the NRC?
a. yes
b. no
c. the NRC does not regulate radionuclidic purity
d. it cannot be determined with the information
e. this is an example of radiochemical impurity rather than radionuclidic impurity - ✔✔b.
no
✔✔if SPECT images taken with a 360d rotation, 32 stops for 15 s/stop, and matric of
64x64 have significant star artifact, which imaging parameter would be best to change
and to correct the image?
a. change the rotation to 180d
