Abstract BACKGROUND AND PURPOSE: Preoperative detection and localization of optic canal invasion (OCI) in suprasellar meningiomas is important to guide surgical decision-making and clinical prognosis. However, OCI assessment is not standardized, and can be challenging to determine radiologically. This study aimed to assess the diagnostic performance of different clinician groups in identifying OCI on preoperative MRI, and the effect of targeted education on performance and interrater reliability.
