In this review article, the authors give basic calculations for renal function assessment in nuclear medicine techniques including evaluation of renal clearance measured by urine and plasma sampling, plasma sampling only, or renal scintigraphy with Patlak-Rutland method and integral method. Furthermore, there are calculations of renal transit time, renal output efficiency and normalized residual activity.
