What Does a Carotid Ultrasound Show?
A carotid ultrasound can show whether plaque buildup has narrowed one or both of your carotid arteries. If so, you might be at risk of having a stroke. The risk depends on the extent of the blockage and how much it has reduced blood flow to your brain.
To lower your risk of stroke, your doctor may recommend medical or surgical treatments to reduce or remove plaque from your carotid arteries.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Carotid Ultrasound, visit www.clinicaltrials.gov.
