[Evaluation of renal function by dynamic CT].
Dynamic CT scans of the kidney were conducted in 57 persons with varied renal function. The results of dynamic CT were used to obtain time-density curves for renal cortex, medulla and aorta. Various parameters were calculated from these time-density curves. Among them, CA ratio, the ratio of the area under the renal cortex curve to the area under the aortic curve, showed the best correlation with creatinine clearance. With these parameters, dynamic CT studies are believed to be useful in evaluating renal function.
