Editor's e-Note
Finding dramatically less invasive treatment for a condition is one of the most impressive aspects of medicine. As a health care journalist, I’ve covered dramatic advances in cataract surgery and endovascular treatment and have read about numerous others. Whether the MR-guided focused ultrasound treatment described in this month’s E-News Exclusive evolves to that point remains to be seen, but incisionless brain surgery is a pretty impressive idea.

HIFU Trial for Treating Essential Tremor Under Way

The Ohio State University Wexner Medical Center is one of six locations nationally studying the safety and effectiveness of using high-intensity focused ultrasound (HIFU) to treat patients suffering from essential tremor as part of a multicenter FDA clinical trial.

Nationwide, 50 patients whose tremors cannot be controlled with medication will be treated with the Exablate Neuro by InSightec, which uses MR-guided focused ultrasound to treat tissue deep in the brain without incisions or radiation. The clinical trial is scheduled to conclude in December 2016. Other centers involved in the research are Brigham and Women’s Hospital in Boston; Stanford Medical Center in Stanford, California; Swedish Medical Center in Seattle; University of Maryland Medical System in Baltimore; and University of Virginia in Charlottesville, Virginia. This minimally invasive treatment is already approved for use in Europe.
