“Amyloid PET scans are a proven tool and can be an important part of Alzheimer’s diagnosis and treatment,” Maria Carrillo, chief science officer of the Alzheimer’s Association, said in a ...
The PET scans were used to look at abnormalities in the brains of people with Alzheimer’s disease, including amyloid plaques and tau tangles, proteins that build up between nerve cells ...
Positron emission tomography (PET) [1] is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
The study also used gold-standard amyloid positron emission tomography, or PET, scans to verify the presence of amyloid and tau in the brains of study participants, and magnetic resonance imaging ...
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.
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 ...
