Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
New IDEAS is an observational, open-label, longitudinal cohort study designed to address the requirements of the CED provisions of the NCD on beta-amyloid PET. Building on the initial Imaging Dementia-Evidence for Amyloid Scanning (IDEAS) study, New IDEAS will evaluate the association between amyloid PET and patient-centered outcomes in an expanded and more ethnoracially and clinically diverse group of Medicare participants presenting with cognitive impairment.
