A vascular examination using high-frequency sound waves to visualize the carotid arteries, located on each side of the neck, produces a visual representation and data about blood flow. These assessments can reveal crucial details about the arterial walls and the velocity of blood moving through them, often providing metrics such as intima-media thickness and identifying potential plaque buildup or narrowing (stenosis).
This non-invasive diagnostic procedure plays a vital role in assessing the risk of stroke. Early detection of arterial narrowing or irregularities allows for timely interventions, such as lifestyle modifications, medication, or surgical procedures, potentially preventing debilitating or life-threatening events. The development and refinement of this technology have significantly improved the ability to identify individuals at risk and contribute to more effective preventative strategies.
