Catalina needs to have a neuroimaging test that will track the activity of her brain, but wants to use a radioactive tracer that is more easily obtained than those used for PET. Which of the following offers the BEST alternative based on Catalina's needs?
A) electroencephalography (EEG)
B) computed tomography (CT)
C) functional positron emission tomography (fPET)
D) single photon emission computed tomography (SPECT)

Question

Quizplus · Accepted Answer

Single photon emission computed tomography (SPECT) uses a radioactive tracer that is easier to obtain than those used in PET. SPECT is also capable of tracking brain activity through the detection of gamma radiation emitted by the tracer. EEG and CT do not use a radioactive tracer to track brain activity, and fPET is not a recognized imaging technique.
