新影像学检查在类风湿关节炎早期诊断中的应用

Application of new imaging examination in early diagnosis of rheumatoid arthritis

目的探讨高频超声(HFUS)联合磁共振成像(MRI)对早期类风湿关节炎(RA)手关节病变的诊断价值。方法收集符合早期RA患者78例,男性21例,女性57例,行双手、双腕关节超声检查及MRI扫描。结果两种检查方法检出各征象比较:关节超声与关节核磁对滑膜炎的检出率相比较,差异无统计学意义P>0.05;关节超声比关节核磁对骨侵蚀的检出率高,差异有统计学意义P<0.05;关节超声对关节腔积液的检出率较关节核磁明显升高,差异有统计学意义P<0.05;两种检查方法对肌腱病变的检测无明显统计学差异,P>0.05。结论关节超声、MRI扫描互相弥补不足,两项检测手段联合应用有助于早期诊断RA。

Objective To investigate the value of high frequency ultrasound(HFUS) combined with magnetic resonance imaging(MRI) in the diagnosis of early rheumatoid arthritis(RA) hand and joint disease.Methods Collection of 78 patients with early RA,21 males and 57 females,Ultrasound and MRI scan of both hands and wrists.Results Comparison of the two signs detected by the two methods,The detection rate of joint ultrasound and joint nucleus to synovitis was not statistically significant(P>0.05).The detection rate of joint ultrasound was higher than that of joint nucleus on bone erosion,and the difference was statistically significant(P<0.05).The detection rate of joint cavity ultrasound was significantly higher than that of joint nucleus.The difference was statistically significant(P<0.05).There was no significant difference in the detection of tendon lesions between the two methods,P>0.05.Conclusion Ultrasound of joints and MRI scans make up for each other.The combination of two detection methods helps early diagnosis of RA.
