Non-invasive estimation of kidney function by X-ray fluorescence analysis. Method for in vivo measurements of iodine-containing contrast media in rabbits

Abstract

It is shown that quantitative determination of the iodine concentration in the soft tissue of rabbits is possible by in vivo measurements using the X-ray fluorescence technique. The influence on the measurements of variable factors such as weight is negligible, due to the use of a well collimated geometry.
