Carotid Doppler ultrasound is a non-invasive diagnostic test that allows the study of the carotid arteries, the main blood vessels that carry blood to the brain.

It is a fundamental examination for the prevention and diagnosis of cerebrovascular diseases, such as stroke.

​

What is it used for?

This test allows:

• evaluation of blood flow in the carotid arteries

• detection of narrowing (stenosis) or blockages

• identification of atherosclerotic plaques

• monitoring of known conditions over time

It is particularly useful in patients with cardiovascular risk factors such as hypertension, diabetes, high cholesterol, or smoking.

​

When is it indicated?

A doctor may prescribe a carotid Doppler ultrasound in the presence of:

• dizziness or episodes of loss of consciousness

• transient neurological symptoms (TIA)

• suspected atherosclerotic disease

• carotid bruits detected during physical examination

• routine follow-up in at-risk patients

• ​

How is the exam performed?

Carotid Doppler ultrasound is a simple, painless, and risk-free examination.

• the patient lies on an examination table

• a gel is applied to the neck area

• the doctor uses an ultrasound probe to visualize the arteries

• the exam usually lasts 15–20 minutes

No specific preparation is required.

​

Is it a safe exam?

Yes. Carotid Doppler ultrasound uses ultrasound waves and not ionizing radiation, so it can be performed safely, even repeatedly over time.

​

What can be seen with carotid Doppler ultrasound?

Thanks to Doppler technology, the exam allows the observation of:

• the structure of the arterial walls

• the presence of plaques or calcifications

• the speed and direction of blood flow

This information helps the doctor assess the risk of cerebrovascular events and determine the most appropriate treatment.

​

After the exam

At the end of the examination, the patient can immediately resume normal activities.

The report is usually provided immediately or within a short time and will be discussed with the referring physician or specialist.

 

In conclusion

Carotid Doppler ultrasound is a key tool for stroke prevention and for monitoring vascular health.

It is a simple, fast, and safe exam that can make a significant difference in the early diagnosis of cardiovascular diseases.
