摘要 目的:应用高频彩色多普勒技术评估骨性关节炎(OA)患者的膝关节关节软骨、滑膜病变的临床诊断价值。方法:应用高频彩色多普勒超声诊断仪对62例(OA)共计124个膝关节及50例正常对照组的100个膝关节进行探查,测量其软骨厚度、边缘及局部轮廓,滑膜厚度和滑膜上血管增生的程度以及关节腔积液情况。结果:超声检出对照组和病例组在关节腔积液、软骨厚度、滑膜厚度、血流信号存在显著差异(P<0.01)。病例组软骨厚度变薄,软骨表面粗糙,滑膜明显增厚,滑膜上血管增生,部分膝关节关节腔有不同程度的积液。结论:(1)高频超声可以清晰地显示极少量的关节积液。(2)高频超声对关节软骨的清晰度、软骨表面轮廓的光滑度以及软骨厚度和软骨的完整性分辨力较高。(3)关节滑膜明显增厚。彩色多普勒对滑膜上血管增生的程度有一定的诊断价值。
