Upon administration, F 18-florbetaben exhibits differential retention in regions that contain certain amyloid deposits. Differences in signal intensity between tissues showing specific and non-specific uptake of F 18-florbetaben allows for the detection of amyloid neuritic plaques in patients being evaluated for Alzheimer's disease, and potentially the detection of amyloid deposits in amyloidosis."}]
