A carotid artery examination using sound waves produces images that allow medical professionals to assess the structure and blood flow within these vital vessels supplying the brain. These images reveal details about arterial wall thickness, plaque presence, and blood velocity, providing crucial information about the risk of stroke. For instance, the visualization might demonstrate a narrowing (stenosis) caused by plaque buildup, indicating reduced blood flow.
This non-invasive diagnostic procedure plays a pivotal role in identifying individuals at risk of cerebrovascular events. Early detection of abnormalities, such as atherosclerotic plaque or significant stenosis, allows for timely intervention and preventative measures, potentially mitigating the risk of stroke. The development and refinement of this imaging technique have significantly enhanced the ability to manage cerebrovascular disease, contributing to improved patient outcomes and a better understanding of stroke prevention.
