Doppler and duplex sonography of the brain-supplying vessels

Description of the examination

Doppler and duplex sonography are ultrasound methods used to examine the blood vessels that supply your brain with oxygen. The flow velocity and condition of the arteries can be assessed using sound waves. While Doppler sonography mainly evaluates acoustic signals, duplex sonography additionally provides a color image of the blood flow.

The examination takes place while lying or sitting, while a special ultrasound probe is placed on the neck region. The device can be used to detect constrictions, deposits or other changes in the vessels at an early stage. This allows diseases such as arteriosclerosis or an increased risk of stroke to be better assessed.

When is this examination necessary?

Doppler or duplex sonography of the brain-supplying vessels is particularly indicated if there is a suspicion of circulatory disorders, risk of stroke or chronic headaches. Even in the case of dizziness or tinnitus, it can be useful to take a closer look at the blood vessels in order to detect any circulatory problems.

This examination can also be used as part of aftercare or follow-up examinations for already diagnosed vascular diseases. Regular checks help to identify changes early and take action in good time.

Is this examination painful or uncomfortable?

Doppler and duplex sonography is a non-invasive procedure and does not cause any pain. You will only feel a slight pressure when the ultrasound probe is placed on the skin. Some people initially find the cool contact gel unusual, but it serves to improve sound transmission.

In addition, acoustic signals are generated during Doppler sonography, which make the flow velocity of the blood audible. This is completely harmless and enables the doctor to optimally assess the vessels.
