The estimation of differential renal function from dynamic renography affects clinical decisions. The estimation requires the kidneys to be delineated with regions of interest. However, in the presence of unilateral hydronephrosis it is not unusual for the affected kidney to be enlarged so that the regions of interest required to delineate the normal and abnormal kidneys are themselves dissimilar in size. The question, which then arises is, will this difference in the sizes of the regions of… CONTINUE READING
