It was concluded that M-mode and two-dimensional color Doppler flow convergence region could be used to quantificate the area of mitral stenosis accurately.
结果表明，M型彩色多普勒血流会聚法与二维彩色多普勒血流会聚法在检测二尖瓣狭窄瓣口面积方面基本可靠，但两者的准确性无显著差异。
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.
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；
