Relationship of GFR using Gamma Camera with Resistive and Pulsatility Index (RI & PI) of Renal Artery using Doppler Ultrasound

Abstract

Background: The aim of this study was to correlate the GFR using Gamma Camera with Resistive and Pulsatility Index (RI & PI) of renal artery using Doppler Ultrasound. Methods: The data of this study was collected from 150 patients both gender referred to nuclear medicine department in Radiation and Isotopes centre -Khartoum (RICK) – Sudan who underwent renal scintigraphy was performed in conjunction with Doppler ultrasound. Results: The PI showed inverse linear relationship with GFR where GFR decreases by 58 ml/ one unit of PI; similarly the RI showed an inverse linear relationship with GFR where it decreased by 141 ml per one unit of RI. Conclusions: The results of GFR using renal scintigraphy can be predicted using RI and PI index and hence the patients who needed further investigation as renal scintigraphy can be identified based on the Doppler results.
