To evaluate the use of a three-dimensional gradient-recalled-echo (GRE) magnetic resonance (MR) imaging sequence in the depiction of lesions of the triangular fibrocartilage (TFC) complex.
MR images of the TFC complex were evaluated in 31 patients who underwent wrist arthroscopy less than 6 months after MR imaging. The results were compared with the arthroscopic findings.
Eleven of 12 full-thickness TFC tears were depicted, but one partial-thickness tear, one abnormal disk, and one normal disk were overstaged. Lesions in the volar and dorsal radioulnar ligament and lesions of the attachments of the TFC complex to the ulna often were overstaged. Lesions of the ulnolunate and ulnotriquetral ligaments often were understaged.
Imaging with the three-dimensional GRE sequence is reliable in the depiction of TFC tears and the exclusion of tears of components of the TFC complex other than those of the ulnolunate and ulnotriquetral ligaments.
评估三维梯度回波（GRE）磁共振（MR）成像序列在显示三角纤维软骨（TFC）复合体病变中的应用。
对31例在MR成像后不到6个月接受腕关节镜检查的患者的TFC复合体MR图像进行评估。将结果与关节镜检查结果进行比较。
12例全层TFC撕裂中有11例被显示出来，但1例部分厚度撕裂、1例异常盘和1例正常盘被过度分期。掌侧和背侧桡尺韧带的病变以及TFC复合体与尺骨附着处的病变常被过度分期。尺月韧带和尺三角韧带的病变常被分期不足。
三维GRE序列成像在显示TFC撕裂以及排除TFC复合体中除尺月韧带和尺三角韧带以外的其他成分的撕裂方面是可靠的。
