Summary
Brief summary (as posted)
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 outcomes (1)
- measure
- Percent of Tumors With Increased Echogenicity (Brightness) Following Contrast-enhanced Sonography
- timeFrame
- 15 min
- description
- 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 outcomes (1)
- measure
- 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
