目的：探讨高频彩色多普勒超声在类风湿性关节炎(Rheumatoid arthritis，RA)膝关节病变诊断中的应用价值。方法：选择健康对照者16例，RA患者40例，应用高频彩色多普勒超声对双侧膝关节进行扫查，观察关节腔积液、滑膜、软骨表面、半月板及关节病变区域血流情况。结果：RA组80个膝关节中60%的关节有关节积液，75%的关节有滑膜增生，62.5%的关节滑膜内显示低速血流信号，22.5%的关节显示软骨磨损，18.8%的关节骨皮质缺损，37.5%有关节半月板发生改变。结论：高频彩色多普勒超声对类风湿关节炎膝关节病变有较高的诊断价值及重要的临床意义。

Objective:To explore application values of high frequency color Doppler ultrasound in the diagno-sis of knee joint disease of rheumatoid arthritis (RA). Methods:All 40 RA patients and 16 healthy people as the con-trol ones were selected, bilateral knee joints of the patients were scanned and examined by high frequency color Doppler ultrasound, to observe blood flow conditions of arthroedema, synovium, cartilage surface, meniscus and le-sion area of the joints. Results: Among RA group, 60% of 80 knee joints had joint effusion, 75% of the joints showed synovial hyperplasia, 62.5%of joint synovium low velocity blood flow signal, 22.5%of the joints cartilage wear, 18.8%of the joints cortical bone defect and 37.5%abnormal changes of joint meniscus. Conclusion:High fre-quency color Doppler ultrasound demonstrates higher diagnostic values and important clinical meaning for knee joint disease of RA.
