1. Become familiar with the MR arthrographic techniques for hip injection and image acquisition. 2. Review the anatomy of the hip though images acquired using MR arthrography. 3. Gain an understanding of the indications for MR arthrography. 4. Become familiar with the MR imaging appearance of pathology commonly encountered with this technique.
ABSTRACT
Hip pain is a common ailment with a variety of causes. A subset of patients will have unexplained, persistent pain despite extensive clinical and radiographic evaluation. Gadolinium-enhanced MR arthrography is a minimally-invasive technique that can significantly improve the specificity and sensitivity of conventional MRI for intra-articular pathology. MR arthrography augments anatomic detail by distending the joint, improving the signal-to noise ratio, and highlighting contiguous pathology. To fully appreciate the benefits of this method, an intimate knowledge of hip anatomy as well as the injection and image acquisition techniques is indispensable. We will describe our techniques and review essential anatomy through schematic diagrams and MR imaging. In addition, we will review indications for MR arthrography of the hip from both the literature and our experience. Finally, we will further demonstrate the utility of this technique through examples of commonly encountered entities.
