Distal radioulnar joint (DRUJ) dysfunction is a common cause of ulnar sided wrist pain. Physical examination yields only subtle clues towards the underlying etiology. Thus, imaging is commonly obtained towards an improved characterization of DRUJ pathology, especially multimodality imaging, which is frequently resorted to arrive at an accurate diagnosis. With increasing use of advanced MRI and CT techniques, DRUJ imaging has become an important part of a musculoskeletal radiologist's practice. This article discusses the normal anatomy and biomechanics of the DRUJ, illustrates common clinical abnormalities, and provides a comprehensive overview of the imaging evaluation with an insight into the role of advanced cross-sectional modalities in this domain.
桡尺远侧关节（DRUJ）功能障碍是尺侧腕部疼痛的常见原因。体格检查仅能提供关于潜在病因的细微线索。因此，通常会进行影像学检查以更好地描述DRUJ病理特征，尤其是多模态成像，它经常被用于做出准确诊断。随着先进的MRI和CT技术的使用增加，DRUJ成像已成为肌肉骨骼放射科医生实践的重要组成部分。本文讨论了DRUJ的正常解剖结构和生物力学，阐述了常见的临床异常情况，并全面概述了影像学评估，深入探讨了先进的横断面成像模式在该领域的作用。
