PET Scans and Disorders
PET Imaging of Depression
The above images demontrate a comparison of a clinically depressed patient (right) compared to a matched control (left). In the color scheme, blue represents less activity (glucose metabolism) while red represents more (glucose metabolism). Note the relative hypoactivity of the cortex on the right with marked hypoactivity of the Prefrontal, Frontal and deeper Basal Ganglia.
PET Scan - Schizophrenia
Notice that in the image of a brain with schizophrenia, some
areas are less red; in other words, less brain activity.
