Comparison of Xenon-133 Washout Curves from the Kidney with Direct Measurement of Renal Venous Outflow

Abstract

In an experimental study the renal blood flow was simultaneously determined by the xenon wash-out technique and by measurement of the renal venous outflow. The degree of agreement was high indicating that determination of the initial slope of the xenon wash-out curve provides a simple, rapid and quantitative means of measuring mean renal blood flow.
