目的探讨三维能量多普勒超声(3D-PDU)判断类风湿关节炎(RA)滑膜病变活动性的应用价值.方法 RA患者44例,分为活动性(23例)和非活动性(21例)两组,分别应用3D-PDU检查腕关节,测量滑膜的体积(V)、滑膜内血管指数(V1),多普勒频谱测量滑膜内动脉血流的收缩期峰值血流速度(PSV)、舒张末期血流速度(EDV)、阻力指数(RI).结果活动性组和非活动性组的V值[(1.73±0.73)cm3对(1.09±0.76)cm3,P=0.008]及VI值(9.53±6.11对3.86±4.99,P=0.000)比较差异有统计学意义;两组间PSV[(16.8±6.29)cm/s对(13.5±8.54)cm/s,P=0.282]、EDV[(5.51 4±1.77)cm/s对(5.03±2.76)cm/s,P=0.539]、RI(0.66±0.07g±O.62±0.08,P=0.095)差别无统计学意义.结论 3D-PDU在判断RA患者滑膜病变活动性中有较高的应用价值,VI值可以作为判断病变活动性的一个有效指标.

Objective To investigate the application value of three-dimensional power Doppler ultrasonography(3D-PDU) for synovial disease in patients with rheumatoid arthritis(RA). Methods Forty four patients with RA were divided into active (23 cases) and non-active (21 cases) groups. 3D-PDU was used in the wrists to measure the volume of synovium(V) ,vascular index(VI) in synovium.and Doppler spectrum was used to measure synovial artery peak systolic blood flow velocity(PSV) , end diastolic velocity (EDV) and resistance index(RI). Results There were significant differences of the V [(1. 73 0. 73) cm3] and VI (9. 53 6. 11) in the group of active patients compared to the V [(1. 09 0. 76) cm3 , P = 0. 008] and VI [(3.86 4.99), P = 0.000] in the ones of inactive patients. No differences were found for PSV [(16. 8 6. 29) cm/s vs (13. 5 8. 54) cm/s, P = 0. 282] ,EDV [(5. 51 1.77) cm/s vs (5. 03 2. 76) cm/s, P = 0. 539] and RI (0. 66 0. 07 vs 0. 62 0. 08, P = 0. 095)in the comparison of two groups. Conclusions 3D-PDU in determining RA disease activity in patients with synovial medium has a higher application value, VI can be used as an effective indicator to determine the disease activity.
