ACR Imaging Criteria for Shoulder Pain

The American College of Radiology (ACR) has published appropriateness criteria for imaging of both traumatic [97] and atraumatic [98] shoulder pain.

Radiographs of the shoulder are the most appropriate initial imaging study in either traumatic or atraumatic shoulder pain. Either magnetic resonance (MR) arthrography or magnetic resonance imaging (MRI) of the shoulder without intravenous (IV) contrast should be performed for atraumatic shoulder pain when instability and labral tear are suspected and initial radiographs are normal or inconclusive. In patients with traumatic shoulder pain, if physical examination and history suggest a prior dislocation event or if there is instability and radiographs are normal, then MRI of the shoulder without IV contrast and MR arthrography are both appropriate studies.
