The American College of Radiology® (ACR®) released an update to its ACR Appropriateness Criteria® (ACR AC), that includes 270 diagnostic imaging and interventional radiology topics with more than 1,300 clinical variants covering 4,000 clinical scenarios and 203 patient-friendly summaries. The update includes 13 new and six revised topics. All topics include a narrative, evidence table and literature search summary.

“The ACR Appropriateness Criteria are an important part of medical practice and serve as an invaluable resource to help radiologists and other clinicians provide the best patient care,” said Ihab Kamel, MD, PhD, chair of the ACR Committee on Appropriateness Criteria. “Hundreds of radiologists and volunteer specialists from more than 50 medical specialties form the expert panels that create and update these criteria to help ensure that patients get the right scan for their condition and avoid unnecessary care.”

ACR AC was first introduced in 1993. The guidelines are developed and reviewed annually by expert panels in diagnostic imaging and interventional radiology. Spanish translations of the ACR AC are now available from Colegio Interamericano de Radiología for 185 topics. More Spanish versions will be posted on a rolling basis as translations progress.
