摘要
类风湿性关节炎(RA)早期诊断与治疗是改善预后的关键,MR技术与新评估系统的发展使RA诊断和分析精细化,弥补了实验室检查的不足。腕关节和掌指关节、近侧指间关节是RA最典型和最常累及的部位。RA早期MR征象包括滑膜炎、骨髓水肿、骨侵蚀、软骨丧失。MR对早期RA腕关节病变检出及诊断准确率均较高,且易于定量评价和纵向比较,能敏感地发现活动性病变与治疗后病变的减轻或吸收。对早期RA腕关节病变的MR检查技术、早期诊断、定量分析及预后评价进行综述。
Early diagnosis and treatment are essential for improving the outcome of rheumatoid arthritis （RA）. New MRI and new scoring system, making precise and quantitative diagnosis and evaluation of RA, can be complementary to laboratory test. Wrist, metacarpophalangeal joint, carpometacarpal joint and interphalangeal joint are most often affected in RA. Early MRI features of RA include synovitis, bone marrow edema, erosions and cartilage loss. MRI can detect early signs of RA in wrist with high sensitivity and accuracy, and can easily and quantitatively monitor lesion response to the treatments. In this review, we summarized values of the wrist MRI in early diagnosis, quantitative analysis and prognosis of RA. [
