Disappearance Rate of Xenon-133 from Dog Liver with Different Arterial Routes of Administration

Abstract
A new technique for selective catheterization of the common and proper hepatic arteries in dogs is described. Using this technique the disappearance rate of 133Xe from they liver after administration of the isotope in the coeliac, the common hepatic and the proper hepatic arteries was studied. From the obtained results it was concluded that when measuring liver blood flow after arterial administration of the tracer substance a selective administration of the isotope in the common artery is preferable.
