WebPET scan of a normal 20-year-old brain. Positron emission tomography (PET) measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream. The emission data are computer-processed to produce 2- or 3-dimensional images of the distribution of the chemicals throughout the brain. [ 6] WebPET scans are a reasonably non-invasive technique of studying inside the brain, as it is relatively painless compared to brain surgery- ethical.
