QUANTITATIVE MEASUREMENT OF CANINE RENAL ARTERIAL BLOOD-FLOW USING DOPPLER ULTRASONOGRAPHY

The aim of this study was to estimate the accuracy of the quantitative measurement of renal blood flow using the non-invasive method, Dopple r ultrasonography. First, we determined a method of approach to the re nal artery in order to detect the rate and pattern of flow, using 8 ad ult beagles under general anesthesia. Secondly, we examined the renal arterial blood Row using the Doppler method and electromagnetic flowme ter using 7 mongrel dogs. A significant correlation (r=0.879; p<0.01) was found between two methods, though the Doppler system tended to ind icate high values than the electromagnetic flowmeter. Our study sugges ts that the Doppler method is a useful non-invasive technique of measu ring renal blood flow in the dog.
