The ACR Appropriateness Criteria® are evidence-based guidelines to assist referring physicians and other providers in making the most appropriate imaging or treatment decision for a specific clinical condition. By employing these guidelines, providers enhance quality of care and contribute to the most efficacious use of radiology.
The guidelines are developed and reviewed annually by expert panels in diagnostic imaging and interventional radiology. Each panel includes leaders in radiology and other specialties. In 2021, there are 216 Diagnostic Imaging and Interventional Radiology topics with over 1030 variants and for our Diagnostic Imaging topics 2400 clinical scenarios.
The ACR allows individuals to use the ACR Appropriateness Criteria for research, scientific, and/or informational purposes only. If you wish to use the ACR Appropriateness Criteria for other reasons, please complete the online ACR permission request form.
