First non-invasive thermal ablation of a brain tumor with MR guided focused ultrasound
Magnetic resonance-guided focused ultrasound surgery (MRgFUS) allows for precise thermal ablation of target tissues. While this emerging modality is increasingly used for the treatment of various types of extracranial soft tissue tumors, it has only recently been acknowledged as a modality for noninvasive neurosurgery. MRgFUS has been particularly successful for functional neurosurgery, whereas...

15 صفحه اولNanodroplet-Mediated Histotripsy for Image-guided Targeted Ultrasound Cell Ablation
This paper is an initial work towards developing an image-guided, targeted ultrasound ablation technique by combining histotripsy with nanodroplets that can be selectively delivered to tumor cells. Using extremely short, high-pressure pulses, histotripsy generates a dense cloud of cavitating microbubbles that fractionates tissue. We hypothesize that synthetic nanodroplets that encapsulate a per...
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 ...
متن کاملTransoesophageal ultrasound applicator for sector-based thermal ablation: first in vivo experiments.
New curative and palliative treatments must be proposed to respond to the bad long-term prognosis of oesophageal cancers. It has been demonstrated that high intensity ultrasound (US) can induce rapid, complete and well-defined coagulation necrosis. For the treatment of this cancer, we designed an applicator that uses an intraductal approach. The active part is an air-backed plane transducer. It...
