Scintigraphic estimation of arterial and portal blood supplies to the liver.

摘要: A technique is described for the measurement of relative magnitudes hepatic-artery and portal-vein components liver perfusion, using a gamma camera on-line computer system. This ratio obtained from analysis time variation in activity on first pass following bolus intravenous injection Tc-99m-labeled radiocolloid. The arterial portal are separated by their times arrival at liver. These evaluated fom variations spleen, left ventricle, kidney. Physiological validation was provided digestion study which normal volunteers showed significant increase component 1 hr after meal to fasting situation.The results compared with tose studies other workers. uncertainties limitations discussed potential clinical uses suggested.
