肾有效血流量(ERBF)是反映肾脏血流灌注状态较直观和较灵敏的重要指标,以往一般采用心前区体表Razzak外推法测定。针对RazzaK法不足,我院脏象研究所医学工程室在其基础上研制了肾图指标回归测定法(简称回归法)。现报道如下。 ERBF检测经典法原理和Razzak外推法 ERBF最早的测定方法是对氨基马尿酸(PAH)清除率法,PAH清除率代表肾有效血流量,~131碘——邻碘马尿酸钠(~131I—OIH)
Renal effective blood flow (ERBF) is to reflect the state of renal blood flow more intuitive and sensitive important indicators, the general use of precancerous body surface Razzak extrapolation method. In view of the lack of RazzaK method, our hospital dirty Institute of Medical Engineering Laboratory developed on the basis of the renal mapping index regression (referred to as regression). Report as follows now. ERBF detection of classical principle and Razzak extrapolation method The earliest determination of ERBF is the amino acid hippuric acid (PAH) clearance rate method, PAH clearance rate on behalf of the renal effective blood flow, ~ 131 iodine-o -hippurate sodium (~ 131I- OIH)
