title: Quantitative evaluation of 99mTc-GSA in the rat liver after ischemia-reperfusion injury.
abstract: 99mTc-DTPA-galactosyl human serum albumin (Tc-GSA) is a new liver-imaging agent which binds specifically to hepatic binding protein. The purpose of this study was to evaluate the usefulness of Tc-GSA in quantitatively evaluating hepatic ischemia-reperfusion injury in the rat. Regional hepatic ischemia was induced by clamping the left hepatic artery and the left portal vein for 5 to 45 min. A hepatic accumulation index (t90) was obtained on the basis of the dynamic data. A significant difference of this index was observed between all ischemic groups and the control. In conclusion, 99mTc-GSA appears useful for evaluating the hepatic ischemia-reperfusion injury.
