D)cerebral angiography

Question

Quizplus · Accepted Answer

Positron emission tomography (PET) uses positively charged isotopes to image the brain's metabolically active tissues. The patient is injected with a radioactively labeled glucose, and as the glucose is metabolized by active brain cells, it emits positrons that are detected by the scanner to create an image of active brain regions.
