Question

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)

Answer 1

SPECT Single-photon emission computed tomography

Explanation:

SPECT is a technique that is used for tomography of the brain to know how the tissue and blood working in the brain. It shows the activity in the brain. This technique helps in diagnoses brain stroke, head injury, ischemia attack, blockage and mental illness like schizophrenia, Alzheimer's, etc.

It is an unclear imaging technique that merges with computed tomography and finds out the problem through a combination of SPECT. Before doing SPECT, an injection is injected into the blood stream. This technique is used to know the blood is flowing in arteries and veins.
