The simultaneous measurement of glomerular filtration rate (GFR) and renal plasma flow (RPF) following renal transplantation by use of functional imaging.

A new method for evaluating renal function using dynamic scintigraphy and deconvolution is described; functional images can be created from the data to quantitate kidney function. Our data are indicating that GFR measurements obtained by this method do not differ from those obtained by classical renal clearance methods. As was expected measurements of renal plasma flow exceed the values of PAH clearance. Additional studies to determine extraction ratios must be done along with direct flow meter measurements.
