Background correction factors in renography with single probe detectors.
The background correction factor was determined with [131I]albumin, FA, in eighty-six patients with various nephro-urological diseases, with [131I]hippuran in eighty unilaterally nephrectomized patients (FH), and in twenty-five patients in whom the renogram showed background configuration, FH, B. FH was approximately the same on the left and the right side, the mean values being 1.39 and 1.35, respectively. FA showed a significant side difference, the mean values being 1.30 and 1.19 on the right side, respectively. FH, B was higher than FH, which shows that some uptake of hippuran can take place in apparently non functioning kidneys.
