Osteochondritis dissecans (OCD) is a localized process that affects the subchondral bone and can progress to the overlying articular cartilage. The cause of this lesion remains elusive. With the vague clinical symptoms and signs of OCD, imaging plays a vital role in making the diagnosis and helping with the prognosis of OCD lesions. This article reviews current imaging modalities for the assessment of OCD including conventional radiography, nuclear medicine, computed tomography (CT), CT arthrography, magnetic resonance (MR) and MR arthrography. The role of imaging in evaluating healing of the OCD and articular congruity after surgical and nonsurgical management is discussed.
剥脱性骨软骨炎（OCD）是一种影响软骨下骨的局限性病变，可发展至上方的关节软骨。该病变的病因尚不明确。由于OCD的临床症状和体征不明确，影像学在OCD病变的诊断及预后判断中起着至关重要的作用。本文综述了目前用于评估OCD的影像学方法，包括传统X线摄影、核医学、计算机断层扫描（CT）、CT关节造影、磁共振成像（MR）及MR关节造影。文中还讨论了影像学在评估OCD愈合情况以及手术和非手术治疗后关节一致性方面的作用。
