类风湿关节炎的影像学诊断进展

DIAGNOSIS OF RHEUMATOID ARTHRITIS IMAGE

类风湿关节炎(RA)是一种病因尚未明确的系统性自身免疫性疾病,主要以侵犯关节滑膜炎为特征,早期的表现常见于小关节(掌指关节、近端指间关节、腕关节等)的对称性、持续性肿胀和压痛,伴进行性关节结构破坏性炎症,是一种致残性极高的疾病,所以早期明确诊断,并予及时药物干预治疗,可有效控制和延缓病变的发展,是防残治残的关键。近年来,影像学检查在RA早期诊断中发挥着很重要的作用,成为国内外学者研究的热点。现就对RA的影像学诊断方法近年来的研究进展进行对比。

Rheumatoid arthritis （ RA ） is a system of a kind of unknown etiology autoimmune diseases. The main assault on joint synovitis characteristic, the performance of the early common in small joint （ metacarpophalangeal joints, proximal interphalangeal joints, wrist joints ） symmetry, persistent swelling and tenderness,with destructive inflammatory joint structure. Is a crippling disease with a high,so early diagnosis,and timely treatment for drug intervention,which can effectively control and delay the development of disease, treatment is prevention of disability and key. In recent years, imaging examination plays an important role in the early diagnosis of RA, become a hot research at home and abroad. Recent research progress on the RA imaging methods are compared.
