Colour Doppler ultrasound can help detect narrowing in the carotid arteries, the major blood vessels that supply blood to the brain. The test uses ultrasound to assess the structure of the arteries and measure the direction and speed of blood flow. It can help identify plaque build-up, narrowing and changes in circulation associated with carotid artery disease. Doctors may recommend a carotid Doppler for patients with certain stroke risk factors or suspected vascular problems. The test is non-invasive and does not use ionising radiation. Aarna Diagnostic Centre provides Colour Doppler imaging for detailed vascular assessment.
