A carotid ultrasound examination uses sound waves to create images of the arteries in the neck that supply blood to the brain. These images provide crucial data about the structure and function of these vessels, including blood flow velocity and the presence of any narrowing or blockages (plaque). For instance, the examination can reveal the degree of stenosis (narrowing) within the carotid artery, which is a key factor in assessing stroke risk.
Evaluation of these neck arteries offers a non-invasive method for identifying individuals at risk for stroke. Early detection of arterial narrowing allows for timely intervention, which can significantly reduce the likelihood of this debilitating event. Historically, diagnosing carotid artery disease often relied on more invasive procedures. The advent of ultrasound technology revolutionized this field, providing a safer and more accessible diagnostic tool. This advancement has played a crucial role in preventative healthcare and improved patient outcomes.
