The Feinstein Institutes for Medical Research announced that the U.S. Food and Drug Administration (FDA) has approved an imaging compound its researchers developed as a diagnostic tool for people with suspected parkinsonian syndromes, including Parkinson’s disease. Fluorodopa F18 (FDOPA) is an injectable compound used during a PET scan to mark the dopaminergic nerve terminals that…

Compared to regular amyloid imaging, fluorodeoxyglucose positron emission tomography (FDG PET), an imaging technique that quantifies brain function by measuring glucose levels, can better assess the progression and severity of cognitive decline in people with Alzheimer’s, and also cognitive impairment, researchers have found.
