摘　　要：采用常规彩色多普勒技术（常规法）和彩色多普勒血流会聚法（会聚法）对５２例生理性二尖瓣返流和８７例病理性二尖瓣返流患者进行了对比研究。结果发现：３３／５２（６３％）例生理性二尖瓣返流和８７／８７（１００％）例病理性二尖瓣返流可于二尖瓣左室面显示血流会聚区；与常规法定量测值（返流束长度和面积）相比，会聚法定量测值（返流率和每搏返流量）在生理性与病理性二尖瓣返流之间的重叠程度较小。表明会聚法在生理性二尖瓣返流的诊断及鉴别诊断中优于常规法。In this study, 52 cases of physiological MR and 87 cases of pathological MR were studied with Flow Convergence Method (FCR)and conventional color flow imaging (CFI). Flow convergence region, which was located in the left ventricular sides of mitral valve, was displayed in 63%(33/52)of physiological MR and 100%(87/87) of pathological MR. The values of mitral regurgitant stroke volume and regurgitant flow rate calculated with FCR was less overlapped between physiological and pathological MR than those of regurgitant jet length and area obtained with CFI. It was demonstrated that FCR method was superior to conventional CFI in the quantification of physiological MR.
