Calculation of renal differential function following renal transplant: retrospective validation of a simplified method.

Objectives: The estimation of differential function (DF) in post-renal transplant patients (PRTPs) is challenging because of the different distances of the native kidneys (NKs) and transplant kidney (TK) to the gamma camera and because current commercial software allows evaluation of only 2 kidneys instead of 3. We retrospectively validated a simplified method (SM) to process renal scans and hypothesized that it is comparable with the reference method (RM).

Patients And Methods: Twelve 99mTc MAG3 renal scintigraphies of 10 PRTPs were performed on a dual-head gamma camera.
