First Phase of Nationwide Study Demonstrates Clinical Impact of Amyloid PET ImagingAmyloid positive PET scan. A first-of-its-kind national study has found that a form of brain imaging that detects Alzheimer’s-related “plaques” significantly influenced clinical management of patients with mild cognitive impairment and dementia. The study revealed that providing clinicians with the results of positron emission tomography (PET) scans that identify amyloid plaques in the brain changed medical management — including the use of medications and counseling — in nearly two-thirds of cases, more than double what researchers predicted in advance of the study. The technique, known as
