To compare direct multi-slice CT arthrography (MSCT-AG) and direct MR arthrography (MR-AG) of the wrist with regard to the depiction of the triangular fibro-cartilage (TFC). Fifteen consecutive patients with ulnar-sided wrist pain suspicious for TFC tear underwent both MSCT-AG and MR-AG of the wrist. Images obtained were evaluated by two radiologists in a blinded fashion for the depiction of six anatomical areas (radial, central and ulnar portion on the proximal and distal side) of the TFC by means of a five-point scoring system (1 = excellent visibility to 5 = not visible). Scores for MSCT-AG and MR-AG were compared using the Student's t-test. Mean scores for MSCT-AG and MR-AG, respectively, were 2.5/2.0, 3.2/2.5 and 2.8/2.4 for the radial, central and ulnar portion of the TFC on its proximal side, and 2.7/2.0, 3.1/2.3 and 2.9/2.4 for the radial, central and ulnar portion on its distal side (n = 15). Paired Student's t-test showed no significant difference between MSCT-AG and MR-AG (P > 0.05). In a first, small series, depiction of the TFC with MSCT-AG is comparable to that of MR-AG. Further evaluation of direct multi-slice CT arthrography of the wrist in a larger patient population would be promising.
为比较多层螺旋CT关节造影（MSCT-AG）和磁共振关节造影（MR-AG）对腕关节三角纤维软骨（TFC）的显示情况。15例连续的怀疑TFC撕裂的尺侧腕关节疼痛患者接受了腕关节的MSCT-AG和MR-AG检查。由两名放射科医生以盲法对所获得的图像进行评估，通过五点评分系统（1 = 显示极佳至5 = 未显示）对TFC的六个解剖区域（近端和远端的桡侧、中央和尺侧部分）进行显示评估。使用Student's t检验比较MSCT-AG和MR-AG的评分。MSCT-AG和MR-AG在TFC近端桡侧、中央和尺侧部分的平均评分分别为2.5/2.0、3.2/2.5和2.8/2.4，在TFC远端桡侧、中央和尺侧部分的平均评分分别为2.7/2.0、3.1/2.3和2.9/2.4（n = 15）。配对Student's t检验显示MSCT-AG和MR-AG之间无显著差异（P > 0.05）。在首个小样本系列中，MSCT-AG对TFC的显示与MR-AG相当。在更大的患者群体中对腕关节直接多层螺旋CT关节造影进行进一步评估可能很有前景。
