Abstract
Summary Twenty-six children underwent a total of 75 99TCm-DTPA scans. Two experienced operators, using different techniques were able to identify parenchyme in 77 of 111 kidneys. Parenchymal regions of interest were drawn by an entirely operator dependent and a relatively operator-independent technique. Transit time analysis, using a matrix algorithm, through the parenchyme of both normal and abnormal kidneys showed a high degree of correlation (r = 0.595, P < 0.001). The technique concurred in the studies for which the analysis could not be applied, generally due to poor technical factors or gross hydronephrosis with insufficient parenchyme to generate a time activity curve. Either technique may be used in clinical practice to identify renal parenchyme for further analysis.Keywords
