Purpose
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

Primary Outcome Measures:
- Percent of Tumors With Increased Echogenicity (Brightness) Following Contrast-enhanced Sonography [ Time Frame: 15 min ]After the systemic iv injection of ultrasound contrast, the real time ultrasound images are visually evaluated, and small intrahepatic tumors are detected on the images. The images pre-contrast and post contrast are compared visually. One tumor per participant was analyzed.
Secondary Outcome Measures:
- Number of Participants With an Increase in Echogenicity (Brightness) of Small Intrahepatic Tumors Following Contrast-enhanced Sonography Based on Tumor Type, Size, Location and Depth [ Time Frame: 15 min ]Visual estimation of the the effect of tumor type, size, location and depth on the conspicuity of small tumors on contrast-enhanced sonography using prior assessment or pathology for tumor type

Detailed Description:
An estimated 75 patients (age 18 years of age or older) will be enrolled from the population of patients who present for ultrasound-guided radiofrequency ablation (RFA) of CT or MRI-confirmed multiple primary hepatocellular carcinoma (HCC) or metastatic carcinoma, with at least one of the tumors being ≤ 1.5 cm in diameter.
