Neuroangiologie (Doppler/ Duplex)
What is a Doppler ultrasound?
A Doppler ultrasound is a test that uses high frequency sound waves (ultrasound) to measure the amount of blood flow through your arteries and veins, usually those that supply blood to the brain.
Vascular flow studies, also known as blood flow studies, can detect abnormal flow within an artery or blood vessel. This can help to diagnose and treat a variety of conditions, including blood clots and poor circulation. A Doppler ultrasound can be used as part of a blood flow study.
A Doppler ultrasound is a risk-free and pain-free procedure that requires little preparation. The test provides your doctor with important information about the flow of blood through your major brain arteries and veins. It can also reveal blocked or reduced blood flow through narrowed areas in the arteries, which could eventually lead to a stroke.
