We reviewed a series of 50 consecutive wrist arthroscopy patients who had been investigated pre-operatively by direct magnetic resonance arthrography and calculated the sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of magnetic resonance arthrography in detecting full-thickness triangular fibrocartilage complex tears, intrinsic carpal ligamentous lesions, wrist synovitis and chondral lesions in the radiocarpal joint. The sensitivities of magnetic resonance arthrography in detecting central triangular fibrocartilage complex tears, peripheral triangular fibrocartilage complex tears, scapholunate ligament tears, lunotriquetral ligament tears, dorsal synovitis and radiocarpal chondral lesions were 89%, 63%, 71%, 100%, 32% and 65%, respectively, and its specificities in detecting these lesions were 91%, 98%, 89%, 94% 94% and 97%, respectively. This study suggests that single compartment direct wrist magnetic resonance arthrography can provide high diagnostic accuracy for full-thickness triangular fibrocartilage lesions, intrinsic carpal ligament tears and chondral lesions in the radiocarpal joint, but that it is much less accurate in diagnosing synovitis of the radiocarpal joint.

我们回顾了连续50例腕关节镜检查患者，这些患者术前均接受了直接磁共振关节造影检查，并计算了磁共振关节造影在检测桡腕关节全层三角纤维软骨复合体撕裂、腕关节内韧带损伤、腕关节滑膜炎和软骨损伤方面的敏感性、特异性、阳性预测值、阴性预测值及总体准确性。磁共振关节造影检测中央三角纤维软骨复合体撕裂、外周三角纤维软骨复合体撕裂、舟月韧带撕裂、月三角韧带撕裂、背侧滑膜炎和桡腕关节软骨损伤的敏感性分别为89%、63%、71%、100%、32%和65%，其检测这些损伤的特异性分别为91%、98%、89%、94%、94%和97%。本研究表明，单腔直接腕关节磁共振关节造影对桡腕关节全层三角纤维软骨损伤、腕关节内韧带撕裂和软骨损伤可提供较高的诊断准确性，但对桡腕关节滑膜炎的诊断准确性则低得多。
