MR-Guided Focused Ultrasound - Stanford Health Care
MR-guided focused ultrasound is a nonsurgical technique to destroy targeted areas of tissue without harming the surrounding tissue. During MRgFUS, 1,000 sound wave beams pass through your bone, fat, muscle, and skin to reach their target. The ultrasound raises the temperature of the targeted area and causes a burn (lesion) in the tissue.
MR-Guided Focused Ultrasound - Penn Medicine
MR-guided focused ultrasound (MRgFUS), also referred to as high-intensity focused ultrasound, is a noninvasive, incisionless procedure. This therapy uses highly focused sound waves as a form of energy to treat essential tremor and symptoms associated with Parkinson's disease, including tremor, rigidity, and slowness of movement.

本期内容给大家介绍一个正在的影像引导治疗系统,它就是 磁共振引导聚焦超声治疗系统,英文可以写作MR-HIFU,俗称磁波治疗或者 磁波刀。 首先特别感谢Profound的张剑博士,他给我提供了很多资料,再次特别感谢。 前文链接: 一.系统概述. 高强度聚焦超声治疗 (H igh I ntensity F ocused U ltrasound, HIFU)是一种比较绿色环保的治疗方法,又叫做高能聚焦超声刀,属于一种无创的治疗手段。 其原理主要是利用高能的超声波聚焦病变区域,通过超声波的空化效应及 …
MR引导聚焦超声治疗子宫肌瘤中国专家共识 - 知乎
MR引导下聚焦超声 (MRgFUS)是一种 无创治疗 子宫肌瘤的 新手段,以MRI为引导,精准地将超声波聚焦于肌瘤瘤体组织,产生65~85 ℃的高温,使肿瘤细胞蛋白质失活、细胞凋亡并凝固坏死,在精准消融肌瘤组织的同时避免损伤治疗区域以外的正常组织。 2000年以来,大量研究对MRgFUS用于子宫肌瘤治疗的安全性及有效性进行了论证[4‑20],2004年美国食品药品监督管理局(FDA)批准MRgFUS用于子宫肌瘤的治疗。 2013年中国FDA批准了MRgFUS在症状性子宫 …

【笔记】MR引导聚焦超声治疗脑肿瘤 - 脑医汇 - 神外资讯 - 神介资讯
聚焦超声 (FUS)是一种新兴的经颅图像引导手术方法,允许超声能量沉积到大脑中的离散目标上。 与神经肿瘤学相关的超声诱导生物效应的范围很广,如热消融、热疗、血脑屏障 (BBB)破坏和组织切片。 许多此类应用在临床前研究和早期临床试验中显示出前景。 此外,许多假定的FUS机制可能同时发生,最终可能适用于针对癌症病理生物学多个方面的合理联合方法。 本章将讨论FUS的机制以及应用于神经肿瘤学的临床前和临床研究的现状。 目前,美国食品和药物管理局 (FDA) …
