高频超声对类风湿关节炎指关节滑膜病变的研究

目的 探讨高频超声诊断类风湿性关节炎(RA)患者指关节滑膜病变的价值.方法 对临床诊断为RA的42例患者及30例健康志愿者双手指关节进行高频超声检查,观察RA患者指关节有无关节积液、滑膜的厚度、滑膜血管过度增生声像图表现及血流特点.结果 RA组共检出256个关节积液,检出率42.38%;检出223个关节滑膜增厚,检出率26.55%;检出51个关节内血管过度增生,检出率6.07%.结论 高频超声能显示RA患者手指关节病变的各种表现,可为临床诊断提供依据.

Abstract：

Objective To study the synovial lesions of finger joint of rheumatoid arthritis (RA) with high frequency ultrasound ( HFUS). Methods HFUS examination of finger joints of both hands were performed in 42 patients with RA and 30 healthy volunteers. The ultrasound findings of the finger joints in RA patients included intra-articular fluid,the thickness of synovial membrane,vascular proliferation. and the blood flow characteristics. Results The intra-articular fluid was found in 256 joints and the detection rate was 42. 38% (256/840). Synovial membrane hyperplasia was found in 223 joints with the detection rate of 26.55% (223/840). The detection rate of HFUS for vascular proliferation was 6.07% (51/840). Conclusions HFUS is an easy, safe and effective method for the diagnosis of RA thus providing useful evidences for clinical diagnosis.
