American College of Radiology (ACR) Appropriateness Criteria and EURO-2000 Guidelines Offer Limited Guidance for MRI Imaging of Pediatric Patients.

Purpose: This study aims to evaluate the clinical scenarios addressed by the EURO-2000 guidelines and the ACR appropriateness criteria for referring children to MRI and assessing the referring physician compliance with both guidelines.

Methods: In January 2022, clinical scenarios reported in the last 1000 consecutive MRI requests for children (0-16 years) in one university children's hospital and two general university hospitals in Belgium, Europe, were retrospectively matched to the EURO-2000 guidelines and ACR appropriateness criteria. The number of clinical scenarios addressed and the justification for MRI referral were independently assessed for both guidelines.
