Functional radionuclide imaging of renal mean transit time and glomerular filtration rate

A technique for functional radionuclide imaging of renal mean transit time and glomerular filtration rate from the results of gamma camera renography with a computer is described. The method uses deconvolution analysis on each pixel time-activity curve. The images of both parameters are of good quality except in cases of very low glomerular filtration rate. They effectively summarize the transit and uptake information available from the renogram and should prove a valuable adjunct in its routine analysis.
