The American College of Radiology (ACR) Task Force on Appropriateness Criteria was established in 1993 and began to develop scientifically-based guidelines to assist referring physicians in making appropriate imaging decisions for a given patient clinical condition in order to provide the College’s perspective on how to best use limited health care resources.
The American College of Radiology (ACR) Appropriateness Criteria® are evidence-based guidelines that have been developed to assist healthcare providers in making the most appropriate imaging decision for a clinical condition. There are 230 topics with over 1,100 variants in the 2017 release. Use of the guidelines will enhance quality of care and contribute to the most efficacious use of imaging.
The guidelines offer advice on the appropriateness of imaging examinations for specific clinical conditions. The imaging is stratified from a score of 9 for the most appropriate imaging examination to 1 for the least appropriate imaging modality. The guidelines also take radiation exposure into account. The suggested imaging is supported by validated scientific evaluation of the current literature and is accompanied by narrative and reference sections.
The guidelines were developed by experts working on panels with committee members representing diagnostic imaging, interventional radiology, radiation oncology, and other medical specialties pertinent to the clinical condition.
There is a process of annual review of selected guideline and revisions are performed on a regular basis. Hence, static images of the guidelines were not provided as they will not adequately reflect any revisions made. Links provided will allow for inclusion of any updates made to the specific Appropriateness guideline you are reviewing.
ACR Imaging Appropriateness Clinical Scenarios
Not all clinical scenarios have dedicated ACR Appropriateness guidelines. Some common clinical scenarios will be presented in this e-Book. Some of these clinical conditions have unique ACR Guidelines associated with them.
