OBJECTIVE. The purpose of this study was to investigate the use of the American Col�lege of Radiology (ACR) appropriateness criteria by referring physicians during decision making about imaging in the management of their patients.
CONCLUSION. There is a low utilization of the ACR appropriateness criteria by cli�nicians when ordering imaging studies for their patients. The ACR has invested a great deal of resources in these criteria and should therefore be aware of information regarding utiliza�tion. Our findings may have implications about how the ACR appropriateness criteria are re�viewed, revised, and disseminated.
