American College of Radiology Imaging Network (ACRIN)

ACR Imaging Network

Since 1999, ACRIN has conducted over 40 clinical trials including landmark breast and lung screening trials. Funded primarily by the National Cancer Institute (NCI), ACRIN investigates scientific questions about cancer detection, staging, and treatment monitoring and response.



The IDEAS study will assess the impact of a brain positron emission tomography (PET) to detect amyloid plaques on patient-oriented outcomes. Medicare will cover amyloid PET when the scan is conducted in accordance with study requirements.

IDEAS is sponsored by the Alzheimer’s Association and managed by the ACR and ACRIN.

Radiation Therapy Oncology Group (RTOG)
