The American College of Radiology has added nine new topics to its influential appropriateness criteria, aimed at helping referrers avoid ordering unnecessary imaging exams.

The newest additions cover conditions including invasive breast cancer, sepsis, and abdominal aortic aneurysm. Following the latest updates, the criteria now include 233 diagnostic and interventional radiology topics with over 1,100 variants pertaining to 3,000-plus clinical scenarios.

“These updates to the ACR Appropriateness Criteria will assist referring physicians and other providers make the most appropriate imaging or treatment decisions for specific clinical conditions,” Mark E. Lockhart, MD, chair of the college committee dedicated to this topic, said in an Oct. 10 announcement.

In addition, the American College of Radiology also released revisions to nine existing topics, including urinary tract infections among children, chronic hand and wrist pain, and management of uterine fibroids.

Expert members of the specialty first created the criteria 30 years ago, and a panel of radiologists reviews them annually to seek out updates or revisions. All nine of the new topics are below. You can find the topic revisions and other information from ACR here.
