The ACR Appropriateness Criteria (AC) 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. Employing these guidelines helps providers enhance quality of care and contribute to the most efficacious use of radiology. The ACR AC was first introduced in 1993 by expert panels in diagnostic imaging and interventional 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 2024, there are 239 Diagnostic Imaging and Interventional Radiology topics with over 1,100 variants and for our Diagnostic Imaging topics 3,900 clinical scenarios.
The ACR allows individuals to use the ACR Appropriateness Criteria for research, scientific, and/or informational purposes only. The AC are not intended to be used as coding guidance for radiologic procedures.
