Carotid ultrasound is a sound-wave study of the arteries in the neck that helps physicians assess plaque buildup, narrowing, and possible stroke-related vascular risk.
Why It Is Ordered
Carotid ultrasound is an office-based study used to evaluate plaque and blockages in the arteries of the neck, with a focus on stroke-related vascular risk.
It is commonly considered when physicians need to better understand stroke risk, prior neurologic symptoms, or signs that vascular disease may be affecting the carotid circulation.
How It Guides Next Steps
Carotid ultrasound helps determine the presence and extent of plaque or narrowing and whether the patient should continue routine surveillance or move into a more intensive vascular workup.
Because it is noninvasive and office-based, it is a practical first-line study when carotid disease is part of the clinical concern.
