Abstract:
Our purpose is to compare ultrasound and fluoroscopic-guided approaches to the glenohumeral joint at the rotator cuff interval for magnetic resonance (MR) arthrography of the shoulder. Forty consecutive patients were prospectively studied. 20 patients underwent ultrasound-guided and 20 patients underwent fluoroscopic guided injection. Successful rate of ultrasound guidance is 95%. No significant difference in pain score and duration of injection between two methods (P>.05). Ultrasound-guided rotator cuff interval injection of the glenohumeral joint for MR arthrography is comparable with fluoroscopic-guided injection. Ultrasound is the preferred method as there is no ionizing radiation.
