The term vascular refers to the blood vessels. Therefore, vascular ultrasound imaging refers to the examination of the body’s circulatory system. This scan studies the speed and volume of blood flow using the Doppler phenomenon.
Strokes secondary to atherosclerotic disease is a major concern. Blood restriction to the brain by a flow-limiting narrowing caused by atherosclerotic disease involving the extracranial carotid arteries is implicated in approximately 20% to 30% of strokes. Possibly 80% of strokes are thromboembolic (blood clot) in origin often with a carotid plaque as the source. A carotid ultrasound is the most non-invasive and cost-effective screening modality to assess and diagnose suspected extracranial carotid artery disease.
