    PET scanning is also used for diagnosis of brain disease, most notably because brain tumors, strokes, and neurondegenerative diseases (such as Alzheimer's disease and Parkinson's disease) all cause great changes in brain metabolism, which in turn causes detectable changes in PET scans. PET is probably most useful in early cases of certain ...

    11 C-PiB is currently the most studied and used radioligand for PET imaging of cerebral Aβ pathology. [2] This technique has been implicated in Alzheimer's disease research whereby scientists involved in this field are able to perform noninvasive in vivo neuroimaging studies using PET scans in brains of individuals with various degrees of dementia.

    Brain scans can now help diagnose and distinguish between different kinds of dementia and show severity. These include magnetic resonance imaging (MRI), computerized tomography (CT), and positron emission tomography (PET). However, it is known that one of the first aspects of Alzheimer's disease is overproduction of amyloid.

  9. PET-CT - Wikipedia

    en.wikipedia.org/wiki/PET-CT

    Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed (co-registered) image.
