Physicians at the University of Calgary, Canada, in partnership with researchers at the Hotchkiss Brain Institute, have successfully performed nine brain surgeries on patients with essential tremor movement disorder without cutting the skin or drilling into the skull. <\/span><\/p>\n

Using magnetic resonance guided focused ultrasound (MRgFUS) technology, the physicians are able to see the brain with real-time imaging and target a beam of high intensity ultrasound to the brain region responsible for tremor. <\/span><\/p>\n

Focused ultrasound technology has been around for a few decades, though it has previously been unable to work through dense substances such as a skull. <\/span><\/p>\n

In the past 10 years, new developments have been achieved to allow the technology to safely pass through bone and tissue to focus on a single point deep inside the brain, using very high power. <\/span><\/p>\n

Physicians can now use the focused ultrasound inside an MRI to image patients and target specific areas of the brain. <\/span><\/p>\n

\u201cWe use that ultrasound technology inside an MRI scanner to actually see where we are so that we can image the patient, who is awake, and see the structures that we\u2019re interested in targeting for the surgery and focus the ultrasound on those points deep inside the brain,\u201d said <\/span>Dr. Bruce Pike<\/span><\/a>, professor in the departments of Radiology and Clinical Neurosciences at the university\u2019s Cumming School of Medicine (CSM). <\/span><\/p>\n

In the case of essential tremor, the most common movement disorder, the MRgFUS technology can be used to perform the same treatment as traditional, invasive surgery, but without breaking the skin. \u00a0<\/span><\/p>\n

\u201cThe conventional surgery that\u2019s been done for quite a while now, called a Thalamotomy, targets a small area inside the thalamus,\u201d said Pike. \u201cThe normal approach is to drill a hole in the skull and insert a probe that passes through the healthy brain tissue all the way down to the thalamus to ultimately heat and destroy the part of the thalamus that is affected. With the focused ultrasound we\u2019re essentially doing the same procedure without having to drill a hole in the skull.\u201d <\/span><\/p>\n

Eighty-five-year-old Elias Pharaon volunteered to undergo treatment for his essential tremor with the MRgFUS technology, and is now able to write his name successfully for the first time in five years. <\/span><\/p>\n
