AL ZHEIMER' S DISE ASE
Facts: PET scans Positron emission tomography (PET) has developed rapidly over recent years as a method for diagnosing Alzheimer’s disease. During the examination, a radio active marker, or radiotracer, is administered to the patient. A PET scanner can then follow the progress of this radiotracer as it is absorbed and distributed around the body’s cells or organs. PET scans are especially well-suited to diseases of the brain, as it is difficult to collect samples inside the brain. Scanning the brain, however, does not harm the patient.
