摘要

Ultrasound (US) medical imaging is safe, inexpensive, portable, and offers excellent spatial resolution and real-time visualization, but its use for advanced diagnostic imaging is hampered by poor soft tissue contrast, which makes the images difficult to interpret. Tissue contrast can be improved by intravascular injection of microbubble ultrasound contrast agents [1], but their short circulation lifetime somewhat limits their broad use in clinical cardiology and radiology. In this study, we overcome this limitation as we significantly prolonged the circulation lifetime of micro-bubbles by making changes in the microbubble lipid shell composition.
