Definition of pet scan in psychology
WebPET scan: [noun] a sectional view of the body constructed by positron-emission tomography. WebMainly, PET scans provide insight into brain and body function and possible sources of dysfunction, and CAT scans can identify areas of dysfunction by locating abnormalities. CAT scans are usually faster than PET scans overall. Fig. 4: Here we can see a composite of images resulting from brain scans using a.) CT, b.)
