In patients with systemic rheumatic diseases, imaging often plays an important role in diagnosis. Erosions of cartilage and bone are among the cardinal features of RA. Plain radiography is used most often to assess for the presence of joint damage, however, other imaging techniques such as contrast-enhanced magnetic resonance imaging (MRI) and ultrasonography are valuable to detect early inflammatory change of joint. In addition, chest CT is essential to detect pulmonary involvement which sometimes can be a main prognostic factor. Finally, arteriograms are helpful in identifying and characterizing a vasculitis of large and medium-sized arteries, in whom an obvious area for biopsy is absent. The present article reviews these imaging techniques.
在系统性风湿性疾病患者中，影像学检查在诊断中常常发挥重要作用。软骨和骨侵蚀是类风湿关节炎的主要特征之一。普通X线摄影最常用于评估关节损伤的存在，然而，其他成像技术，如对比增强磁共振成像（MRI）和超声检查，对于检测关节早期炎症变化很有价值。此外，胸部CT对于检测肺部受累至关重要，肺部受累有时可能是一个主要的预后因素。最后，动脉造影有助于识别和表征大中型动脉的血管炎，对于这些患者，不存在明显的活检部位。本文综述了这些成像技术。
