| Abstract: | Quantitative hepatic scintigraphy is a noninvasive test for measurement of relative arterial and portal blood flow to the liver. This technique has been used to evaluate human patients with known or suspected liver tumors or diffuse hepatocellular disease. A computer program to assess the hepatic perfusion index (HPI) in the normal dog is described. Factors affecting study quality and accuracy include injection technique, cardiac function, patient position, respiration, gross patient motion, and user intervention during data processing. HPI for a group of 12 normal dogs was 0.9±0.4 (X±SD). Quantitative scintigraphy could be used to evaluate dogs with primary or secondary liver tumors, portacaval shunts, or chronic liver disease |
