Magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) is a well-established technology that has been developed during the last decade and is currently used in the treatment of a diverse range of neurodegenerative brain disorders and neuropsychiatric diseases. This innovative noninvasive technology uses nonionizing ultrasound waves to heat and thus ablate brain tissue in selected targets. In comparison with other lesioning and surgical techniques, MRgHIFU has the following advantages: noninvasive, an immediate clinical outcome with no risk of long-standing ionizing radiation injury, no need for general anesthesia, and no device implantation.
- Focused ultrasound
- high-intensity focused ultrasound
- transcranial-focused ultrasound Key Message: Magnetic resonance guided focused ultrasound lesioning is a safe clinical alternative.
