彩色多普勒超声估测肾血流

Renal Blood Flow Measurements by Doppler Color Flow lmagimg

９０例正常人应用彩色多普勒超声方法估测肾血流，其中７４例检出，说明这一方法检出率高。应用体外实验的两种方法对彩色多普勒超声估测肾血流的可靠性验证，实验结果相关密切，提示彩色多普勒超声测定肾血流可靠性好。从实验数据散点图的离散度小可看出彩色多普勒超声测定肾血流这一方法是可信的。

The renal arterv blood now in 90 nor-mal subjects were measured by Doppler color flowimaging(DCFI).74 individuals from 90 normals wereidentified.These outcome suggests that the methodhas high identification rate. Simultaneously,the reli-abilit of DCFI in measurement of rena blood flowwas verified by two methods of experiment in vitro.The test has close regression correlation. It showsthat DCFI in measurement of renal blood flow istrustworthy,The test number scattered spot drawingappears the small dispersed degree which shows thatmethod of measuring renal blood flow by DCFI is be-lievable.
