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...
متن کاملAugmentation of limb perfusion and reversal of tissue ischemia produced by ultrasound-mediated microbubble cavitation.
BACKGROUND Ultrasound can increase tissue blood flow, in part, through the intravascular shear produced by oscillatory pressure fluctuations. We hypothesized that ultrasound-mediated increases in perfusion can be augmented by microbubble contrast agents that undergo ultrasound-mediated cavitation and sought to characterize the biological mediators. METHODS AND RESULTS Contrast ultrasound perf...
متن کاملCavitation detection for brain imaging and therapy
Background/introduction Cavitation-mediated therapies for the brain, such as ultrasound-induced Blood-Brain barrier opening and sonothrombolysis for the treatment of stroke, are being increasingly investigated. Robust methods for monitoring and controlling cavitation are necessary for safe translation of these techniques into clinical practice. This talk will review our work detecting and mappi...

متن کاملUltrasound 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...
