In clinical practice, the conventional radiography is still the radiologic method for the diagnosis of rheumatoid arthritis (RA). Moreover, it provides a quick overview of the symptomatic joints to narrow the differential diagnosis and to evaluate progression. RA is a polyarticular disease with bilateral and symmetric involvement of the peripheral joints, especially small joints, and less frequently, the cervical spine. The radiologic features are soft tissue swelling, periarticular osteoporosis, erosions, loss of joint space, and in advanced disease, osteolysis and typical subluxations or deformities, such as ulnar deviation.
在临床实践中，传统放射摄影仍是诊断类风湿关节炎（RA）的放射学方法。此外，它能快速呈现症状关节的概况，以缩小鉴别诊断范围并评估病情进展。RA是一种多关节疾病，外周关节呈双侧对称受累，尤其是小关节，颈椎受累较少见。放射学特征包括软组织肿胀、关节周围骨质疏松、侵蚀、关节间隙变窄，在疾病晚期还包括骨质溶解以及典型的半脱位或畸形，如尺侧偏斜。
