Better diagnostics could reduce risky surgery for asymptomatic carotid stenosis

New research from Neurologist Dr. David Spence of The University of Western Ontario has shown that using 3-D ultrasound to identify ulcers in the carotid arteries is an effective way to pinpoint the small number of high-risk patients with asymptomatic carotid stenosis (ACS) who would benefit from surgery to prevent stroke.
