Estimation of the hepatic blood flow in the dog with the Xe133 and hydrogen wash-out Au190 -colloid uptake techniques and with the electromagnetic flowmeter.
In dogs anaesthetized with pentobarbital hepatic blood flow measured with electromagnetic flowmeters placed on the hepatic artery and the portal vein was 142 +/- 10.2 ml.min(-1).100 g(-1). The flow estimated with the hydrogen clearance technique was 64 +/- 4.4 per cent, with the Xe133 wash-out technique 78 +/- 7.4 per cent and by the uptake of colloidal radiogold 96.5 +/- 5.0 per cent of the direct measurement. In the flow range between 50 and 344 ml.min-1. 100 g-1 the respective correlation coefficient between HBF measured with the hydrogen clearance technique and with the flowmeter was 0.733, between Xe133-HBF and flowmeter HBF 0.785 and between Au198-colloid HBF and the directly measured HBF was 0.815.
