Influence of statistical noise on the determination of the single kidney 99Tcm-DTPA clearance.
Single kidney clearance can be obtained using the 99Tcm-DTPA complex and the scintillation camera. In order to evaluate the influence of statistical noise on the determination of the clearance, several non-noisy curves were constructed, simulating renal, background and precordial curves. Poisson noise was added to these curves and the clearance results were compared to those obtained on the original curves. It was shown that, in so far as a moderate curve smoothing was used, the statistical noise did not interfere considerably with the results of the renal clearance.
