Marika needs to have a neuroimaging test that will track the activity of her brain,along with changes in her brain oxygen levels.Which of the following offers an alternative to PET scans,with the advantage of using radioactive tracers that are easier to monitor?
A)electroencephalography (EEG)
B)computed tomography (CT)
C)functional positron emission tomography (fPET)
D)single photo emission computed tomography (SPECT)

Question

Single photo emission computed tomography (SPECT) is an imaging technique that can track the activity of the brain while also monitoring changes in brain oxygen levels. SPECT uses different radioactive tracers than PET scans, and these tracers are easier to monitor, making the procedure safer for patients. EEG is another neuroimaging technique, but it only measures electrical activity in the brain and does not provide information about oxygen levels. CT scans are useful for detecting structural abnormalities in the brain, but they do not track brain activity or oxygen levels. While functional PET scans can track brain activity and oxygen levels, they use more complex and less readily monitored radioactive tracers than SPECT.
