Bilateral Carotid Artery Atherosclerotic Plaque Duplex Ultrasound
This non-invasive duplex ultrasound evaluation uses high-frequency sound waves to assess the bilateral carotid arteries—the paired major vessels that carry oxygenated blood directly from the heart’s left ventricle to the brain—for atherosclerotic plaque buildup, vessel narrowing, and abnormal blood flow that elevates risk of stroke and systemic cardiovascular events. The exam also captures images of adjacent cervical veins and lymphatic vessels in the neck region to provide a comprehensive overview of upper cervical cardiovascular and lymphatic function, supporting diagnosis of both cerebrovascular disease and broader cardiovascular pathology.
This non-invasive bilateral carotid artery duplex ultrasound uses high-frequency sound waves to evaluate atherosclerotic plaque, vessel patency, and blood flow to assess stroke and systemic cardiovascular disease risk.
