ACR Appropriateness Criteria


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 AC are not intended to be used as coding guidance for radiologic procedures. Learn more »

Provide Feedback

The feedback site allows us to track and manage feedback from a variety of sources. One focus of this site is to capture insights from partners who are not directly involved in the ACR AC development and review processes. Feedback and comments on any topic may be submitted at any time, including during the focused commenting period scheduled for two months after each release. We do our best to provide timely responses to all input.

Patient Summaries

The Journal of the American College of Radiology (JACR), in collaboration with the ACR AC Patient Engagement Subcommittee, has launched Patient Summaries as a new publication category, representing an important, new initiative to have patients (laypersons) summarize AC recommendations for patients. It is anticipated the ordering physicians and radiologists will welcome these publications, as the summaries are intended to help patients understand what tests are appropriate for their situation, and are designed to help ordering physicians and radiologists better communicate the reason they are requesting, or performing, a particular imaging test.
