    Abstract:
    The hepatic blood flow (HBF) of patients with liver disease was measured by per-rectal portal scintigraphy with the use of 133Xe. To analyze the time-activity curves of the liver and portal vein, washout curves of the liver were plotted, and from those, the HBF and the ratio of the HBF of the right lobe of the liver to that of the left lobe (R/L ratio) were calculated. The HBF were 143 +/- 17 ml/100 g/min in 5 patients with chronic inactive hepatitis, 119 +/- 20 ml/100 g/min in 4 patients with chronic active hepatitis, and 73.2 +/- 23.4 ml/100 g/min in 7 patients with cirrhosis of the liver. All of four patients whose HBF was under 100 ml/100 g/min and whose R/L ratio was under 1.0 had cirrhosis of the liver. Only one of the 9 patients whose HBF was over 100 ml/100 g/min and whose R/L ratio was over 1.0 had cirrhosis of the liver. The results suggested that per-rectal portal scintigraphy is a useful and noninvasive method to measure the hepatic blood flow.
