X-ray images exposed in neutral position and radiocarpally centred are essential in imaging of the distal radioulnar joint (DRUJ). The anatomic orientation of the DRUJ is favourable for acquiring transaxial scans to display its anatomy, subtle derangements, osteoarthritis and intra-articular fractures free from superpositions. The triangular fibrocartilage complex (TFCC) is the most important stabilizer of the DRUJ. Provided that a focused clinical indication is given, high-resolution images are acquired, and an intra-venous or intra-articular contrast-agent is applied, all TFCC structures and destabilizing lesions can be displayed with the use of CT and MRI.
在中立位且以桡腕关节为中心拍摄的X线片对于桡尺远侧关节（DRUJ）的成像至关重要。DRUJ的解剖方位有利于进行横轴位扫描，以显示其解剖结构、细微紊乱、骨关节炎和关节内骨折，且无重叠。三角纤维软骨复合体（TFCC）是DRUJ最重要的稳定结构。只要有明确的临床指征，获取高分辨率图像，并使用静脉内或关节内造影剂，利用CT和MRI就能显示所有TFCC结构和导致不稳定的病变。
