Computer-assisted dynamic renal studies were performed on a group of 14 mongrel dogs before and after the induction of unilateral renal artery stenosis. Ninety-second technetium-99m diethylenetriaminepentaacetic acid ((/sup 99m/Tc)DTPA), 15-min (/sup 99m/Tc)DTPA, and 30-min iodine-131 orthoiodohippurate ((/sup 131/I)hippuran) time-activity curves were analyzed and correlated with reduction of renal blood flow as measured by electromagnetic flow probe and PAH clearance techniques. For blood flow reductions greater than 33%, the (/sup 99m/Tc)DTPA studies were judged diagnostic of unilateral renal artery stenosis in all cases, whereas the (/sup 131/I)hippuran time-activity curves were indicative of stenosis in only six of ten studies. Thus, in this model we find the computer-assisted 90-sec (/sup 99m/Tc)DTPA renal flow study to be superior to conventional (/sup 131/I)hippuran renography in the diagnosis of moderate-to-serve unilateral renal artery stenosis.
