Primary outcomePrimary: Percent of Tumors With Increased Echogenicity (Brightness) Following Contrast-enhanced Sonography — 8 tumor
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
