Marika 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 Marika's needs?
A) electroencephalography (EEG)
B) computed tomography (CT)
C) functional positron emission tomography (fPET)
D) single photo emission computed tomography (SPECT)

Quizplus · Accepted Answer

SPECT uses a radioactive tracer that is more easily obtained than those used for PET and can track the activity of the brain. EEG measures the electrical activity of the brain and is not a neuroimaging test that tracks brain activity. CT scans provide structural images of the brain and do not track brain activity. fPET tracks brain activity but uses a radioactive tracer similar to PET, which is not easily obtained.
