This study explores the number of incidental findings in a large (N= 11,810) multi-site brain MRI study (Adolescent Brain Cognitive Development). 3T baseline scans were reviewed by board-certified neuroradiologists for incidental findings. Approximately 21% of the scans had incidental findings with 3.7% warranting non-urgent clinical referrals and 0.2% warranting urgent clinical referrals. The remaining 17% of the scans with incidental findings did not require follow up.
