August 5, 2015 — The Alzheimer’s Association announced the launch of a new website for the upcoming Imaging Dementia — Evidence for Amyloid Scanning (IDEAS) study. The site enables patients, caregivers, providers, and positron emission tomography (PET) facilities to get up-to-date study information, learn how to get involved and receive updates on enrollment timelines and pathways.
Site visitors will find answers to frequently asked questions and can subscribe to be notified as IDEAS information and resources become available. The site includes information for various stakeholders, including:
Patients — Study overview, patient eligibility and consent information
PET Facilities — How to get involved, basic participation requirements, reimbursement Information and locations
Referring providers — How to get involved and specialist qualifications
The IDEAS study will assess the impact of a brain PET scan to detect amyloid plaques on patient-oriented outcomes. These plaques are a core feature of Alzheimer’s disease in patients with mild cognitive impairment (MCI) or dementia of uncertain cause. Medicare will cover amyloid PET when the scan is conducted in accordance with the IDEAS-Study requirements.
IDEAS is sponsored by the Alzheimer’s Association and managed by the American College of Radiology (ACR) and American College of Radiology Imaging Network (ACRIN).
