Your carotid arteries carry blood from your heart to your brain. When plaque silently builds up inside them, stroke risk rises dramatically — with no warning signs until it is too late.[1] This 45-minute scan changes that.
Many people have never had this scan before. Here is exactly what happens — no surprises, no anxiety.
No radiation. No needles. No discomfort. An ultrasound uses sound waves — the same technology used in obstetric imaging. It is entirely safe and non-invasive.
Just show up. No fasting, no medication changes. Wear a low-collar shirt or remove any necklaces beforehand.
Completely painless. The sonographer gently places a small probe on the sides of your neck and captures detailed images of both carotid arteries.
We can see exactly how blood is moving through your arteries and identify any areas of narrowing or plaque buildup.
Your images are reviewed by a board-certified cardiologist who specializes in vascular disease.
A clear written report explains your plaque burden, degree of stenosis if any, and recommended next steps.
These conditions often develop without symptoms for years. Early detection changes the outcome dramatically.
Narrowing of the artery that restricts blood flow to the brain — a leading cause of ischemic stroke.[2]
Fatty deposits inside the artery walls. Even small amounts can break off and cause a stroke.
Unstable plaque characteristics that significantly increase near-term stroke risk.
Early artery wall thickening that predicts future cardiovascular risk before symptoms appear.[3]
Abnormal flow patterns caused by partial blockages that can be detected before they become critical.
Unusual artery positioning or branching patterns important to identify before any procedures.
We built BlackPoint Diagnostics because quality cardiovascular imaging shouldn't require a hospital visit, a referral, or a weeks-long wait. Our sonographer performs cardiovascular imaging daily alongside physicians — this is clinical-grade diagnostics delivered with genuine convenience.

Warning signs include sudden dizziness, loss of balance, numbness on one side of the body, difficulty speaking, or a sudden severe headache. A temporary episode — called a TIA (mini-stroke) — is a critical warning that a stroke may follow. A carotid duplex ultrasound evaluates the arteries that supply blood to the brain and can detect dangerous plaque buildup before a stroke occurs.
High cholesterol accelerates plaque buildup in the carotid arteries, narrowing the vessel and increasing stroke risk. A carotid duplex ultrasound measures the degree of narrowing and identifies unstable plaque — information that cannot be obtained from a cholesterol panel alone.
A sound in the neck — called a carotid bruit — is caused by turbulent blood flow through a narrowed artery. When a physician detects a bruit, a carotid duplex ultrasound is the next diagnostic step to determine the degree of stenosis and whether intervention is needed.
