Abstract

We evaluated the renal function could be estimated by the visual analysis of the perfusion images of Tc-99m DTPA renal scan. Renal scan, creatinine clearance(CCr) and serum creatinine(s-Cr) were obtained in 105 patients. Intensity of renal activity(RA) at 6 sec perfusion image after the first visualization of abdominal aortic activity(A or A) was considered as the parameter for estimating renal function. Intensity of RA was scored from grade(Gr.) 1 to 3(Gr. 1: RAsplenic activity(SA), Gr. 2: RA A or A, Gr. 3: RA60 mL/min. The P.P.V. of Gr. 2 RA was 92% for s-Cr from 1.5 to less than 3.5mg/dL and 83% for CCr value from 20 to less than 60mL/min. The P.P.V. of Gr. 3 RA was 95% for s-Cr3.5mg/dL and 95% for CCr<20mL/min. As the intensity of RA of perfusion images decreased, renal function more decreased. We could detect renal dysfunction by visual analysis of perfusion images of renal scan.
