摘要: Abstract Radioactivity versus time curves were generated for the first pass of technetium-99m pertechnetate through left ventricle, kidneys, spleen and liver, after a 20 mCi peripheral intravenous bolus injection. The rate change radioactivity in these organs before recirculation is proportional to blood flow organ. hepatic perfusion index, defined as ratio portal total flow, was correlated with angiographic grade perfusion. index seven normal subjects 66.0 ± 3.4 percent (mean standard error mean), 22 cirrhotic patients decreasing grades 1 4 54 4.6, 37 2.6, 17 4.7 3 1.1 percent, respectively. correlation between calculated highly significant (p
