Summary

The purpose of this study is to determine the efficacy of the Definity (perflutren lipid microsphere Injectable Suspension) ultrasound contrast agent in identifying small tumors (hepatomas \& metastases) within the liver. Primary objective: To estimate the increase in conspicuity of small intrahepatic tumors with contrast-enhanced sonography Secondary Objectives: To estimate the effect of tumor type, size, location and depth on the conspicuity of small tumors on contrast-enhanced sonography
