reagents is omitted from its preparation? - ✔✔c. methylene blue stabilizer
✔✔78. Intravenous morphine can be used when performing gall bladder imaging to
improve the specificity of the exam by causing: - ✔✔b. a rise in common bile duct
pressure which will cause a backflow of bile into the gallbladder

include a record of: - ✔✔. uniformity

the whole body bone scan on this individual, you should pay special attention to: - ✔✔c.
hot spot artifacts on the patient's skin and clothes
, ✔✔According to the NRC, 99Mo contamination in 99mTc eluate must be measured how
often? - ✔✔d. After the first elution

patient's medical history is pertinent to the interpretation of the image? - ✔✔a. The
patient is receiving morphine for pain
✔✔85. The circumferential profile technique used to quantitate SPECT myocardial
perfusion studies is performed on what set of tomographic slices? - ✔✔a. short axis
✔✔86. When 99mTc-labeled red blood cells are used for gastrointestinal bleeding
localization, a left anterior oblique view of the abdomen can better visualize the: - ✔✔e.
descending colon vascularity.
✔✔87. Based on the graph of a spectrum of radionuclide X, what is the full width at half
maximum (FWHM)? - ✔✔c. 20
✔✔88. The hematocrit value for the blood sample shown below would be what percent?
- ✔✔b. 40
✔✔89. What is a possible cause for multiple hot spots in a 99mTc MAA image of the
lungs? - ✔✔e. Blood drawn back into the syringe forms radioactive thrombi.
✔✔90. The artifact in the image below is most likely from imaging with which isotope? -
✔✔a. 99mTc
✔✔91. A hospitalized patient received 100 mCi of Na 1311. The earliest possible
discharge date for this patient can best be determined by: - ✔✔c. performing external
dose rate measurements of the patient with an ionization chamber survey meter.
✔✔92. After processing a stress/rest myocardial perfusion study, an area of decreased
activity is noted in the location of the inferior wall on both the stress and rest images.
This is probably due to: - ✔✔b. the patient having a thick diaphragm.
✔✔93. A vial of pyrophosphate contains 15.4 mg stannous pyrophosphate in 3 ml of
saline solution. The standard dose for blood pool imaging is 0.2 mg/kg. What volume in
ml is required for a 65-kg adult? - ✔✔d. 2.8
