Noninvasive Treatment of Breast Cancer Using High-Intensity Focused Ultrasound
Breast conserving surgery is a standard procedure for breast cancer since 1970. Now noninvasive therapy with few complications is preferred. High-intensity focused ultrasound (HIFU) has been developed to ablate solid tumor or cancer noninvasively. Its clinical outcome on breast cancer in China and Europe as well as the induced vascular destruction and immune response are summarized. In summary,...
متن کاملNoninvasive functional neurosurgery using transcranial MR imaging-guided focused ultrasound.
UNLABELLED Transcranial magnetic resonance imaging-guided focused ultrasound (tcMRgFUS) is a novel technique to supplement the spectrum of established neurosurgical interventions. In contrast to traditional ablative procedures, tcMRgFUS is noninvasive and entirely imaging-guided with continuous temperature measurements at and around the target in real time. It has no trajectory restrictions and...
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 کاملMR-guided high-intensity focused ultrasound for noninvasive cancer treatment
Magnetic resonance (MR)-high-intensity focused ultrasound (HIFU) is an innovative, noninvasive tumour ablation technique. MR imaging and focused ultrasound are combined allowing real-time anatomic guidance and temperature mapping during treatment. Recently, the volumetric ablation approach has been introduced in order to reduce treatment length and provide more homogeneous tumour ablation. Afte...
متن کاملHigh-intensity focused ultrasound for noninvasive functional neurosurgery.
Transcranial magnetic resonance (MR)-guided high-intensity focused ultrasound (tcMRgHIFU) implies a novel, noninvasive treatment strategy for various brain diseases. Nine patients with chronic neuropathic pain were treated with selective medial thalamotomies. Precisely located thermal ablations of 4mm in diameter were produced at peak temperatures of 51 degrees C to 60 degrees C under continuou...
