CT renal planimetry: effectiveness in the evaluation of individual renal function.
Computed tomographic (CT) renal planimetry was used to study individual renal function in 32 adult patients with urologic disease. CT results were well-correlated to reference methods (r = 0.88, P < 0.001), which were radionuclide studies (N = 9) or separate creatinine clearance (N = 23). The difference between planimetric data and reference methods did not exceed 14% in any case and was less than 10% in 26 cases.
