In which radiopharmaceutical is 99mTc left in the valence state of +7?
(a) Sulfur colloid
(b) Macroaggregated albumin
(c) MAG3
(d) Sestamibi
(a) Sulfur colloid
A technologist receives a request for a patient to receive 153Sm for palliation of pain from bone
metastases. The patient has a leukocyte count of 3,500 and 40,000 platelets. What should happen
next?
(a) The order should be changed to 89Sr.
(b) The therapy should be delayed until the platelet count is
at least 60,000.
(c) The therapy should be delayed until the leukocyte count
is below 2,400.
(d) The 153Sm dose should be ordered.
(b) The therapy should be delayed until the platelet count is
at least 60,000.

A sulfur colloid kit requires the addition of 1-3 ml containing no more than 500 mCi of 99mTc
pertechnetate. In addition, 1.5 ml of Solution A must be added before boiling, and 1.5 ml of Solution
B must be added after cooling. If the kit is cor- rectly prepared, what is the maximum concentration
of 99mTc it could contain?
(a) 83 mCi/ml
(b) 125 mCi/ml
(c) 167 mCi/ml
(d) 500 mCi/ml
(b) 125 mCi/ml
A Hine-Duley phantom is useful for testing the spatial resolu- tion and spatial linearity with only one
image.
(a) True
(b) False
(b) False

The advantage of a lung ventilation scan performed with 133Xe is:
(a)The ability to match perfusion and ventilation positioning
(b) The ability to detect delayed washout
(c) The ability to perform the exam at the patient's bedside
(d) The ability to perform perfusion before ventilation
without increasing the dose given for the ventilation study
(b) The ability to detect delayed washout
A diphosphonate kit contains 180 mCi of 99mTc in 30 ml when it is prepared at 8:00 a.m. Immediately,
a 20 mCi dose is withdrawn for a bone scan. If the patient arrives late at 9:30 and half the volume is
accidentally discharged, how much volume from the kit must now be added to the syringe to
correct the dose to 20 mCi? (No other doses have been withdrawn meanwhile, and the decay factor
for 1.5 h is 0.841.)
(a) 1.5 ml
(b) 2.0 ml
(c) 2.3 ml
(d) 2.5 ml
(e) 2.7 ml
(c) 2.3 ml
