In January 2011, an FDA advisory committee unanimously recommended that Avid's PET scan technique be approved for use. The advisory committee included a qualification requiring Avid to develop clear guidelines establishing when the tests had spotted enough of the amyloid plaque to make a diagnosis of Alzheimer's.

“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 ...
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.
A substantial proportion of patients with a positive florbetaben PET scan progressed to AD-dementia over a 2-year and 4-year time frame. At 4-year follow-up, 88% (21/24) of individuals with MCI and positive florbetaben uptake converted to clinical dementia due to AD, whereas none of 21 florbetaben-negative individuals with MCI experienced a ...
The 90% accuracy of the study’s combined blood test was confirmed via a spinal fluid tap, which along with an amyloid PET scan is currently the only gold-standard scientific method other than ...
The agency proposes to remove the once-per-lifetime limit on beta amyloid PET scans that restricted their use to clinical trials. The changes will permit Medicare beneficiaries to seek ...
PET scans showed that the compound was retained in areas of the cerebral cortex known to contain significant amyloid deposits from post-mortem examinations. The initial human study of PiB was expanded to include 16 Alzheimer's disease subjects and 9 cognitively normal controls, the report of which was published in 2004 in the Annals of Neurology.
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.
