5.The patient may undergo a PET scan, an M.R.I. or a spinal tap — tests that detect the presence of two proteins in the brain, amyloid plaques and tau tangles, both associated with Alzheimer’s. 6.According to Alzheimer’s Disease International, only 20% to 50% of people with the...

Information on the market implications of the CMS decision is provided. In June 2012, Eli Lilly requested CMS coverage of PET for amyloid plaque detection using Amyvid. Jo Ellen Slurzberg of JR Associates explains the dilemma posed by the request to CMS.EBSCO_AspMedical Device Daily...
There is good evidence that elevated amyloid-β (Aβ) positron emission tomography (PET) signal is associated with cognitive decline in clinically normal (CN) individuals. However, it is less well established whether there is an association between

4e) but to some extent clustered around the periphery of congophilic amyloid deposits, suggesting it was bound to a halo of soluble Aβ aggregates, which has been reported to surround the fibrillar core of amyloid plaques41 (Fig. 4f)....
While the presence of beta-amyloid plaques in the brain may be a hallmark of Alzheimer’s disease, giving patients an amyloid PET scan is not an effective method for measuring their cognitive function, according to a new study from researchers in the Perelman School of Medicine at the Universit...

IODO PRECURSOR FOR A PET IMAGING AGENT OF AMYLOID PLAQUESThe invention relates to a precursor for a [ 18 F]-labeled PET tracer for imaging of Alzheimer's Disease, its synthesis and the process for preparing the respective [ 18 F]-labeled PET tracer....
but a negative scan indicating sparse to no amyloid plaques "is inconsistent with a neuropathological diagnosis of AD at the time of image acquisition; a negative scan result reduces the likelihood that a patient's cognitive impairment is due to AD," the company notes in a statement issued ...
