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
