Arthrography is Superior to Magnetic Resonance Imaging for Diagnosing Injuries of the Triangular FibrocartilageFrom the Division of Hand Surgery, Department of Orthopedics, Nagoya University School of Medicine, Nagoya, and the Department of Radiology, Toyota Memorial Hospital, Toyota, Japan Correspondence: K. Shionoya MD, Division of Hand Surgery, Department of Orthopedics, Nagoya University School of Medicine, 56 Tsurumaicho Shouwaku Nagoya, Aichi 466, Japan. The ability of single-injection radiocarpal arthrography and magnetic resonance imaging (MRI) to detect full-thickness tears of the triangular fibrocartilage were compared with wrist arthroscopy in 102 patients with wrist pain. The sensitivity of arthrography was 85%, and of MRI was 73%. Specificity was 100% for arthrography and 72% for MRI. Accuracy was 92% for arthrography, and 73% for MRI. Although future advances in MRI technology will probably improve its usefulness, single-injection wrist arthrography currently is superior to routine MRI for the detection of full-thickness triangular fibrocartilage tears.
