A review of a planar gallium scintigraphy presents suspicious areas of uptake in the abdomen. What is the next step?
Select Your Answer:
Single-photon emission computed tomography (SPECT) imaging improves localization and therefore characterization of suspicious findings on planar imaging, and it can be performed without additional radiation to the patient.
Encouraging voiding does not improve or clarify gallium scintigraphy because the activity after 24 hours is excreted in the bowel, not renally. It would be helpful for the patient to evacuate his bowels, take laxatives or have an enema.
There is no role here for sulfur colloid imaging and subtraction.
A WBC scan may be needed at some point for further clarification if the gallium scan was being done to localize infection, but it is not the first choice because it takes time and adds costs and radiation.
