We reports the accuracy of direct Magnetic Resonance Arthrography (MRA) in detecting Triangular Fibrocartilage Complex (TFCC), Scapho-Lunate Ligament (SLL) and Luno-Triquetral Ligament (LTL) tears using wrist arthroscopy as the gold standard. We reviewed the records of all patients who underwent direct wrist MRA and subsequent arthroscopy over a 4-year period between June 2007 and March 2011. Demographic details, MRA findings, arthroscopy findings and the time interval between MRA and arthroscopy were recorded. The scans were performed using a 1.5T scanner and a high resolution wrist coil. All scans were reported by a musculoskeletal radiologist. Sensitivity, specificity, positive and negative predictive values (PPV & NPV) were calculated.Introduction
