Abstract

Magnetic resonance-guided focused ultrasound surgery (MRgFUS) of the brain can be expected to revolutionize central nervous system (CNS) disease treatment and change the treatment paradigm in multiple fields including but not limited to neurooncology, neurosurgery, radiation oncology and the clinical neuroscience, in general. MRgFUS can be used to non-invasive thermally ablate brain tumors; its non-thermal effects cause blood brain barrier disruption that can be leveraged to increase the targeted delivery of drug, gene, and other therapeutics agents into the brain. FUS has been shown to play a part in the treatment of certain functional neurological disorders such as movement disorders, epilepsy, or pain, and may have a role in functional neurosurgery. FUS-induced arterial occlusion effects can be exploited in treating hemorrhaging vessels and vascular malformations. By contrast, FUS has thrombolytic effects that can be used in stroke. Thus, MRgFUS spans a significant spectrum of the clinical neurosciences and has the ability to significantly change numerous fields.
