Provide Feedback
Our enhanced commenting web site allows us to better track and manage feedback coming from a variety of sources.
One focus of this site is to capture insights from stakeholders who are not directly involved in the ACR Appropriateness Criteria development and review processes. For two months after each release, the College conducts a focused commenting period to collect feedback related to the new and revised topics included in the release.
However, feedback and comments on any topic may be submitted at any time. Anyone can suggest new topics, splitting or grouping topics together, suggest new references or evidence for the expert panel to consider, ask questions or clarifications, or comment on the ACR AC process and methodology. We will do our best to provide timely responses but eventually all input will be reviewed and addressed.
Please let us know if you have any suggestions for the Review page so we can collect and address better your input and comments. . Click here to access the commenting site »
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.
