The purpose of a carotid duplex examination primarily revolves around its ability to screen for atherosclerosis and stroke. This non-invasive imaging technique combines the use of traditional ultrasound with Doppler technology to visualize the carotid arteries in the neck. By examining blood flow and detecting any plaque buildup within the arterial walls, the carotid duplex can identify areas of stenosis (narrowing) or occlusion that may limit blood flow to the brain, thus playing a critical role in stroke prevention.

The carotid duplex also helps clinicians evaluate the velocity of blood flow within these vessels, which can indicate the severity of any blockages and the risk of cerebrovascular events. Early detection of arterial disease through this examination allows for timely intervention, potentially reducing the risk of serious complications like stroke.
