目的：探讨3.0T MRI 三维脂肪抑制扰相梯度回波技术(3D fs SPGR)对正常三角纤维软骨复合体(TFCC)的大体结构(三角纤维软骨盘、桡尺远端掌背侧韧带、尺月韧带、尺三角韧带、尺侧副韧带、尺侧腕伸肌腱鞘及关节盘同系物)的显示情况。方法成人健康志愿者15例(30例腕关节)，分别用轴位快速自旋回波 T1加权像(FSE T1 WI)或 T2加权像(T2 WI)，冠状位快速自旋回波脂肪抑制 T2加权像(FSE fsT2 WI)，冠状位3D fs SPGR 对30例腕关节进行常规扫描，后将3D 序列图像重建，由2位医师阅片达成一致并记录观察 TFCC 大体结构的显示率。结果3D fs SPGR 重建后的冠状面、横断面图像对关节盘、关节盘同系物、桡尺远端掌背侧韧带及尺侧腕伸肌腱鞘全部显示，尺月韧带、尺三角韧带在冠状面上全部显示，在横断面显示分别为93.3%(28/30)、96.7%(29/30)，尺侧副韧带横断面、冠状面显示分别为83.3%(25/30)、86.7%(26/30)。结论冠状位3D fs SPGR 序列可以作为观察腕关节 TFCC 及其周围韧带的常规序列。

Objective To investigate the value of MR 3D fs SPGR(three-dimensional fat-suppressed spoiled gradient echo se-quence)in displaying the general structure of normal triangular fibrocartilage complex(triangular fibrocartilage disc,palm dorsal dis-tal radioulnar ligament,ulnolunate ligament,ulnotriquetral ligament,ulnar collateral ligament,extensor carpi sheath and articular disc homologues).Methods 1 5 normal adults(30 carpals)were examined withconventional sequences including axial fast spin-echo T1-weighted images (FSE T1 WI)or T2-weighted images (T2 WI),coronal fat-suppressed fast spin-echo T2-weighted images (FSE fsT2 WI)and coronal 3D fs SPGR.As well,3D image reconstruction was performed.Two experienced radiologists read the images with an agreement and recorded the display rate of general structure of TFCC.Results Triangular fibrocartilage disc,articular disc homologuespalm,dorsal distal radioulnar ligament,and extensor carpi sheath were totally showed on coronal and cross sections.Ulnolunate liga-ment and ulnotriquetral ligament were totally seen on the coronal plane,and the display rates on cross-section were 93.3%(28/30), 96.7%(29/30)respectively.Ulnar collateral ligament was seen on cross-section and coronal plane 83.3%(25/30),86.7%(26/30)re-spectively.Conclusion Coronal 3D fs SPGR sequence can be used as a regular sequence for observing TFCC and the surrounding lig-aments .
