Ultrasound imaging with microbubble in the liver

A Targeting Microbubble for Ultrasound Molecular Imaging

RATIONALE Microbubbles conjugated with targeting ligands are used as contrast agents for ultrasound molecular imaging. However, they often contain immunogenic (strept)avidin, which impedes application in humans. Although targeting bubbles not employing the biotin-(strept)avidin conjugation chemistry have been explored, only a few reached the stage of ultrasound imaging in vivo, none were report...

Ultrasound microbubble destruction imaging in acute middle cerebral artery stroke.

BACKGROUND AND PURPOSE Cerebral perfusion imaging in acute stroke assists in determining the subtype and the severity of ischemia. Recent studies in perfusion models and in healthy volunteers have shown that ultrasound perfusion imaging based on microbubble destruction can be used to assess tissue perfusion. We applied ultrasound microbubble destruction imaging (MDI) to identify perfusion defic...

Superharmonic microbubble Doppler effect in ultrasound therapy

The introduction of microbubbles in focused ultrasound therapies has enabled a diverse range of non-invasive technologies: sonoporation to deliver drugs into cells, sonothrombolysis to dissolve blood clots, and blood-brain barrier opening to deliver drugs into the brain. Current methods for passively monitoring the microbubble dynamics responsible for these therapeutic effects can identify the ...

Assessment of track microbubble flow signals on contrast-enhanced ultrasound with perflubutane following percutaneous liver biopsy.

OBJECTIVE It is important to detect post-liver biopsy hemorrhage early and confirm hemostasis in the clinical setting. Contrast-enhanced ultrasound (CEUS) is a sensitive and highly specific tool for detecting active bleeding. The aim of this study was to investigate the rate of detection of track microbubble flow signals on CEUS with perflubutane following liver biopsy and to assess the disappe...
