Abstract
A new method for estimation of the renal functiolL
was developed using three-comparts model analysiswith
gamma camera system.
The rate constants of the plasma flows between
the compartments were obtained from the time
activity curves of three regions of interest (ROO.
the aorta, the left and right kidney.
The ratio of these rate constants was shown to
be proportional to the ratio of the glomerular Jletration rate (GFR) to the effective renal plasma
flow (ERPF), thus providing the estimated filtration
fraction (FF).
In 50 normal subjects, the ratio of the rate constants
(k 3/k, or k,/k,) was O. 19±0. 04 for left kidney
and O. 19±0. 05 for right kidney. In 25 patients with
abnormal renal function, these ratios were larger
than those in normal groups (0. 33±0. 09) or smaller
(0.1l±0.02).
This method is simpler and more non-invasive
than other methods. And it provides a quantitative
evaluation method of the renal function.
