摘　　要：目的探讨定量分析不同病程类风湿性关节炎(RA)患者手腕部骨关节磁共振成像(MRI)特征和疾病严重程度。方法将本院收治的65例RA患者作为研究对象,根据患者病程的不同,分为A组(病程不超过2年)34例,B组(病程超过2年)31例。观察两组患者MRI征象,并采用定量分析软件比较两组骨髓水肿范围和滑膜炎范围等差异。结果两组骨髓水肿、滑膜炎、腱鞘炎和骨侵蚀征象发生率比较,并无明显差异(P>0.05)。两组骨髓水肿范围和滑膜炎范围比较,并无明显差异(P>0.05)。结论经MRI检查可清晰显示RA患者手腕部骨关节特征性改变,并采用定量分析软件能够为RA患者病情严重程度的评估提供可靠的量化信息。Objective To quantitatively analyze magnetic resonance imaging(MRI)characteristics and disease severity of wrist joints in patients with rheumatoid arthritis(RA)of different course.Methods A total of 65 patients with RA admitted to our hospital were divided into 34 patients in group A(course of disease less than 2 years)and 31 patients in group B(course of disease more than 2 years)according to their course of disease.MRI findings of the two groups were observed,and quantitative analysis software was used to compare the differences between the two groups in the range of bone marrow edema and synovitis.Results There was no significant difference in the incidence of bone marrow edema,synovitis,tenosynovitis and bone erosion between the two groups(P>0.05).There was no significant difference in the range of myeloedema and synovitis between the two groups(P>0.05).Conclusion MRI examination can clearly show the characteristic changes of wrist bone and joint in RA patients,and quantitative analysis software can provide reliable quantitative information for the evaluation of the severity of RA.
