Answer

For arthrography, dye is injected into the glenohumeral joint and postinjection radiographs are taken to assess the integrity of the glenohumeral joint.

  • Can be used to evaluate rotator cuff tears (A finding of dye escaping out of the joint and into the subacromial space is diagnostic of a full-thickness rotator cuff tear.)

  • Advantages - Can be used in conjunction with a CT scan to evaluate intra-articular pathology (eg, Bankart tears) and has a low cost

  • Disadvantages - Size of the tears cannot be quantified, patient is exposed to radiation and contrast dye, procedure is invasive
