Osteoarthritis (OA) is the most prevalent joint disorder in the elderly, and there is no effective treatment. Imaging is essential for evaluating the synovial joint structures (including cartilage, meniscus, subchondral bone marrow and synovium) for diagnosis, prognosis, and follow-up. This article describes the roles and limitations of both conventional radiography and magnetic resonance (MR) imaging, and considers the use of other modalities (eg, ultrasonography, nuclear medicine, computed tomography [CT], and CT/MR arthrography) in clinical practice and OA research. The emphasis throughout is on OA of the knee. This article emphasizes research developments and literature evidence published since 2008.
骨关节炎（OA）是老年人中最常见的关节疾病，目前尚无有效的治疗方法。影像学对于评估滑膜关节结构（包括软骨、半月板、软骨下骨髓和滑膜）对于诊断、预后和随访至关重要。本文描述了常规放射摄影和磁共振成像（MR）的作用和局限性，并考虑了在临床实践和 OA 研究中使用其他模态（例如，超声、核医学、计算机断层扫描[CT]和 CT/MR 关节造影）。重点始终放在膝关节 OA 上。本文强调了自 2008 年以来的研究进展和文献证据。
