MR arthrography of the hip: comparison of IDEAL-SPGR volume sequence to standard MR sequences in the detection and grading of cartilage lesions.

Purpose: To compare the diagnostic performance of iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL)-spoiled gradient-recalled echo (SPGR) with that of standard magnetic resonance (MR) arthrography sequences for detecting and grading cartilage lesions within the hip joint during MR arthrography.

Materials And Methods: Following institutional review board approval, 67 consecutive hip MR arthrograms were retrospectively reviewed independently by three musculoskeletal radiologists and one musculoskeletal fellow. IDEAL-SPGR images and the two-dimensional images, the latter from the routine MR arthrography protocol, were evaluated at separate sittings to grade each articular surface of the hip joint.

Correlation of MRI findings with clinical findings of trochanteric pain syndrome.

Objective: Greater trochanter pain syndrome due to tendinopathy or bursitis is a common cause of hip pain. The previously reported magnetic resonance (MR) findings of trochanteric tendinopathy and bursitis are peritrochanteric fluid and abductor tendon abnormality. We have often noted peritrochanteric high T2 signal in patients without trochanteric symptoms.

Cryoablation in the musculoskeletal system.

Pain palliation can be challenging in patients with metastases to the musculoskeletal system, and conventional therapy can be less than optimal for pain management. Recent advances in technology have allowed for the addition of image-guided ablation to the armamentarium for treating musculoskeletal metastases. This article focuses on one such technique, percutaneous cryoablation, and the experiences with this technique at the authors' institution.

Utility of percutaneous treatment in spontaneous renal artery dissection: case report and review of the literature.

Spontaneous renal artery dissection (SRAD) is a relatively rare entity that has been described in several case reports and small series in the medical literature. The condition is best diagnosed with angiography, with renal ischemia or infarction a common complication. Conservative medical management, surgical intervention, and percutaneous intervention are all discussed in the current literature.
