OBJECTIVE: A variety of radiographic views have been described in the literature for the initial imaging of nonacute shoulder pain. Multiple articles have also discussed the best next imaging test if radiographs do not show the diagnosis, especially the use of unenhanced MRI, MR arthrography, CT arthrography, and ultrasound. The purpose of this article is to examine the evidence for the most helpful radiographic views and the best imaging test after radiographs for different clinical presentations of chronic shoulder pain.
CONCLUSION: The recommended radiographic views and best next imaging test after the radiograph depends on the clinical diagnosis. Ultrasound is generally preferred over MRI for evaluating chronic rotator cuff pain, whereas MR arthrography, preferably with abducted and externally rotated images, is most accurate for imaging chronic symptoms from a suspected labral tear or instability.
