Abstract:
The primary functions of the kidney are: (i) to get rid of the body waste materials that are either ingested or produced by metabolism, and (ii) to control the volume and composition of the body fluids. Herein, we provide a noninvasive methodology to assess physiological function of the kidneys. For this purpose, we analyze the renograms with 2-compartmental modelling of the kidney-renal outflow system, and therefrom compute the amount of flow of renal radionuclide into and out of the renal pelvis compartment. The derived information of uptake (k/A) and washout (e(beta/2V2)t sinhAt) rates can be of considerable use. The paper provides a number of case studies for the verification of the derived system governing equations against clinical renograms.
