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)

Single photo emission computed tomography (SPECT) can use a radioactive tracer that is more easily obtained than those used in positron emission tomography (PET), making it a good alternative for Marika's needs. EEG and CT do not track brain activity at the same level of detail as neuroimaging tests that use tracers, and fPET still requires a radioactive tracer.
