Fractional rate as unjustly neglected approach to gamma-camera measurement of renal and plasma clearance.
Abstract
Presenting plasma and renal clearance as fraction of plasma volume cleared per unit time is subject to controversy. The aim of the contribution was to validate 3 methods for measurement of fractional plasma and renal clearance in dynamic renal scintigraphy.
It was found that the methods for fractional plasma clearance perform well in posterior-view dynamic renal scintigraphy while those for renal clearance perform better in AC conjugate view. They should be considered as technically simple and robust alternatives to regression methods.
