MRI引导聚焦超声(MRgFUS)手术是一种无创热消融方法,使用磁共振成像(MRI)进行目标定义、治疗计划和能量沉积的闭环控制。将FUS和MRI集成为治疗输送系统使我们能够真实的实时定位、靶向和监测,从而在不损伤正常结构的情况下消融靶组织。这种精确度使MRgFUS成为良性和恶性肿瘤手术切除或放射治疗的有吸引力的替代方案。MRgFUS已被批准用于治疗子宫肌瘤,目前正在进行临床试验,用于治疗乳腺癌、肝癌、前列腺癌和脑癌,以及缓解骨转移疼痛。除了热消融之外,FUS(使用或不使用微泡)可以暂时改变血管或细胞膜的通透性,并释放或激活各种化合物,用于靶向药物递送或基因治疗。作为一项颠覆性技术,MRgFUS提供了新的治疗方法,并可能导致患者管理和多个医学学科的重大变化。
MRI-guided focused ultrasound (MRgFUS) surgery is a noninvasive thermal ablation method that uses magnetic resonance imaging (MRI) for target definition, treatment planning, and closed-loop control of energy deposition. Integrating FUS and MRI as a therapy delivery system allows us to localize, target, and monitor in real time, and thus to ablate targeted tissue without damaging normal structures. This precision makes MRgFUS an attractive alternative to surgical resection or radiation therapy of benign and malignant tumors. Already approved for the treatment of uterine fibroids, MRgFUS is in ongoing clinical trials for the treatment of breast, liver, prostate, and brain cancer and for the palliation of pain in bone metastasis. In addition to thermal ablation, FUS, with or without the use of microbubbles, can temporarily change vascular or cell membrane permeability and release or activate various compounds for targeted drug delivery or gene therapy. A disruptive technology, MRgFUS provides new therapeutic approaches and may cause major changes in patient management and several medical disciplines.
