An image showing three positron emission tomography (PET) scans.
An image showing three positron emission tomography (PET) scans. Red and yellow areas correspond to areas of high metabolic activity. The top image shows the brain activity of a normal subject. The scan at the bottom left represents the reduced brain activity of a patient with HIV-induced dementia. It shows reduced brain activity in several brain regions. The scan at bottom right is from the same patient following treatment with azidothymidine (AZT), where the brain activity becomes closer to the normal.
