Effects of ultrasound and ultrasound contrast agent on vascular tissue
BACKGROUND Ultrasound (US) imaging can be enhanced using gas-filled microbubble contrast agents. Strong echo signals are induced at the tissue-gas interface following microbubble collapse. Applications include assessment of ventricular function and virtual histology. AIM While ultrasound and US contrast agents are widely used, their impact on the physiological response of vascular tissue to v...
متن کاملCollapse Dynamics of Ultrasound Contrast Agent
Ultrasound contrast agents (UCAs) are micron-sized gas bubbles encapsulated with thin shells on the order of nanometers thick. The damping effects of these viscoelastic coatings are widely known to significantly alter the bubble dynamics for linear and low-amplitude behavior; however, their effects on strongly nonlinear and destruction responses are much less studied. This dissertation examines...

متن کاملThe angiogenic response is dependent on ultrasound contrast agent concentration
OBJECTIVE Ultrasound (US) and ultrasound contrast agents (UCAs) provide a way to noninvasively induce targeted angiogenesis. However, there exists a lack of understanding regarding the mechanisms of this process that has impeded progress. This study sought to characterize the angiogenic response, by both exploring the role of UCA concentration ([UCA]) in bioeffect induction at 0 days post expos...
متن کامل“Non-thermal” ablation using focused ultrasound and an ultrasound contrast agent
Background/introduction The combination of focused ultrasound and an intravenously-injected microbubble ultrasound contrast agent offers the ability to reduce the power needed to ablate tissue, which is particularly important for targets in the brain since it can eliminate skull heating. When applied at a low duty cycle so that bulk tissue heating does not occur, the mechanical effects induced ...
