An improved method of estimating the portal venous fraction of total hepatic blood flow from computerized radionuclide angiography.

摘要: The measurement of portal venous flow to the liver is important in evaluation patients for shunt surgery. A previous report described a method using slope analysis hepatic radionuclide angiograms generate an index relative flow, which correlated well with angiographic grades perfusion. present describes refinement bolus administration and modification technique that appear reflect true more accurately. total 109 studies was performed, including seven normal 80 cirrhotic patients. reproducible (r = 0.998) showed good correlation perfusion -0.906).
