 CEUSContrast specific software optimized for Sonazoid will be used or both vascular and Kupffer phase imaging. The focus will be set below the lesion of interest for vascular phase imaging and at 4-8 cm for the left lobe and 8-10 cm for the right lobe for Kupffer phase imaging. The lesion of interest was imaged from 15 seconds before injection to 1 minute after injection vascular phase imaging. No further scanning will be performed until the Kupffer phase imaging, which will begun 10 minutes after the injection.
