MR Arthrogram Case Study

Our case study of the month is an MR Arthrogram of the right shoulder. The patient is a 29 year old female with symptoms of chronic right shoulder pain with a history of right shoulder surgery. The MRI scan shows there is a small tear of the anterior-inferior labrum.

MR Arthrogram Procedure:

  • MRI of the shoulder is performed without contrast material
  • The images are evaluated by the radiologist
  • The patient’s physician may order an MR Arthrogram of the shoulder if a tear is suspected
  • For the MR Arthrogram, contrast is injected into the shoulder joint space under fluoroscopic (x-ray) guidance
    • This allows the radiologist to better see the structures in the shoulder joint
    • When the contrast agent is seen in the joint space under fluoroscopic guidance, the MR scan is performed on the patient
  • If there isn’t a tear, the contrast material should remain within the shoulder joint space and be absorbed into the tissue
  • If the contrast leaks out of the joint space, then the radiologist can determine the size and extent of any tears or other issues
