Determination of total, divided and regional tubular clearance and excretion by compartmental analysis of camera renograms.
A method to analyze the camera renogram is described in a mathematical manner. It is based on a 6-compartment model, which simulates the hippurate in vivo kinetics. Results are transfer rate constants from which the tubular clearance (by multiplying with the plasma volume) and additionally excretory parameters can be derived. The method is quick and simple and needs a gamma-camera and a small data processing system only, but no special equipment and no blood sampling.
