View Pet Scan Of Alzheimer's Brain UK. The special pet scans use radioactive tracers to highlight amyloid protein plaques in the brain, which are a hallmark of alzheimer's disease. Until recently, the only way to determine if someone's brain had the plaques.

A pet scan that measures uptake of sugar in the brain significantly improves the accuracy of diagnosing a type of dementia often mistaken for alzheimer's disease, a new study has found. But as evidence mounts that brain damage from alzheimer's begins years before people develop symptoms, worried patients and their families may start turning to pet scans the drugs approved for alzheimer's, primarily aricept and namenda, have modest benefits in some patients for a limited time. An increase in blue and green colors shows decreased brain metabolic activity due to alzheimer's disease.

Pet scans may help detect alzheimer's before symptoms begin. These are pet scans from three different people, a person with alzheimer's disease, a normal older person who has no amyloid in the brain. A brain positron emission tomography (pet) scan is an imaging test of the brain. Combining pet and mr scans mean that patients do not have to commit to more than one scan.

In a pet scan, a radioactive substance is used to highlight the most active areas of the brain by measuring which cells are neurologists say pet is an excellent tool for distinguishing between alzheimer's and frontotemporal dementia, which can look similar in the early.
