Editorial Commentary: There Is Value in Standardizing the Position of the Arm During Magnetic Resonance Imaging Arthrogram of the Shoulder When Evaluating for Suspected Instability (and It Doesn't Have to Be Painful to the Patient!).

Abstract

Evaluating and treating a shoulder with suspected instability remains a challenge for all. Most authors and surgeons would agree that clinical history and physical examination of the patient are the most important aspects of this evaluation. Over the past 15 years, however, radiographic imaging has become a much more prevalent (and essential) component. Magnetic resonance imaging arthrogram has become the gold standard to evaluate a patient for suspected instability and is currently considered the most appropriate advanced study by the American College of Radiologists to do so in both traumatic and atraumatic presentations.
