MRI在早期类风湿关节炎中的应用价值

摘要

Rheumatoid arthritis (RA) is a kind of systemic autoimmune disease presenting with multiple, nonspecific inflammation of the joints. It is a chronic progressive disease. RA is one of the common diseases that cause workforce loss and disability. The early diagnosis and treatment of RA has an important influence on prognosis. MRI has many advantages, such as high soft tissue resolution, multi-layer, multi-planar and multi-sequence imaging, no radiation. It can show many pathological changes of the early RA, including synovitis, bone marrow edema, bone destruction and cartilage degeneration. MRI might be of high value in early diagnosis, predicting progression, evaluation of therapeutic effect and prognosis of RA. In this paper, the value of MRI in early RA was reviewed, aiming to improve the application of MRI in its clinical practice.%类风湿关节炎（RA）是以多发性、非特异性关节炎症为主要表现的自身免疫性疾病，呈慢性、进行性发展，是导致劳动力丧失及致残的常见疾病之一，早期诊断及治疗对其预后具有重要影响。MRI具有软组织分辨力高，可多层面、多方位、多序列成像，无电离辐射等优点，能够很好地显示早期RA滑膜炎、骨髓水肿、骨质破坏、软骨变性等病理改变，对于该病的早期诊断、进展预测、预后监测及疗效评价具有重要价值。综述MRI在早期RA中的应用价值，以扩大其应用范围。
