Tests · Carotid ultrasound

The arteries
that feed your brain.

A carotid ultrasound measures plaque and narrowing in the two arteries in your neck that supply the brain, which is the most direct stroke-risk measurement a screening program contains. It takes about fifteen minutes, uses no radiation and needs no preparation.

What it finds, and what it does not

What it finds, and what it does not.

Plaque thickness and the degree of narrowing in the carotid arteries, plus blood-flow velocity. Narrowing found here is one of the few screening results with a clear, established action attached to it.

It looks at two arteries in the neck and says nothing directly about the arteries inside the skull or in the heart. A clear carotid scan is not a clear cardiovascular system.

Suitability

Who it suits, and who should not have it.

Suits: Adults over 45, anyone with high blood pressure, high cholesterol, diabetes or a smoking history, and anyone with a family history of stroke. It is also the sensible first vascular test if you are choosing only one.

Should not have it: Nobody on safety grounds. It is the least invasive test in any program.

In context

How it differs from the related test.

A carotid ultrasound looks at the vessels feeding the brain from outside the skull. A brain MRA looks at the vessels inside it. The carotid scan is cheaper, faster and radiation-free; the MRA sees aneurysms and intracranial narrowing the carotid scan cannot reach.

Which tier includes it

FAQ

Questions worth asking before you book.

Is this the same as a stroke screening?
It is the largest single part of one, not the whole thing. A fuller stroke work-up adds brain imaging and vessel imaging inside the skull. MediOne sells exactly that as a stroke screening add-on at ≈₩800,000.
Do I need to prepare?
No fasting and no preparation. Wear something that leaves the neck accessible.
