Computer processing of radionuclide renogram and use ofdeconvolution method to calculate renal transit time

摘要

A programme using a matrix algorithm for deconvolution analysis ofthe renogram has been developed at the All India Institute of MedicalSciences, New Delhi. The programme plots the retention function for eachkidney and computes minimum transit time, mean transit time and transittime index for them. Any prolongation of the transit time of theradioactive tracer through the various regions of the kidney becomes animportant and reliable diagnostic tool for upper urinary tractobstruction
