The American College of Radiology (ACR) has released an update to its ACR Appropriateness Criteria (ACR AC), which includes 211 diagnostic imaging and interventional radiology topics with more than 1,000 clinical variants covering approximately 1,900 clinical scenarios. This update includes 13 new and five revised topics. All topics include a narrative, evidence table and a literature search summary.

The ACR AC was first introduced in 1993 by expert panels in diagnostic imaging and interventional radiology to help providers make the most appropriate imaging or treatment decisions for specific clinical conditions. These guidelines are developed and reviewed annually.

The ACR is designated by the Centers for Medicare and Medicaid Services as a qualified Provider-Led Entity.
