Duplex sonography of arteries supplying the brain: a detailed picture of arterial structure and function
Duplex sonography in the Neuro Praxis Düsseldorf
Duplex sonography of the arteries supplying the brain is a medical examination that examines the blood flow in the arteries in and around the brain. It combines Doppler ultrasound technology with conventional ultrasound technology to provide a detailed picture of artery structure and function.
The exam is performed by placing a transducer on the skin of the neck to examine the arteries supplying the brain. The transducer emits sound waves that bounce off the arterial wall, providing an image of arterial structure. The Doppler effect is used to measure blood flow speed and direction.
Duplex sonography of the arteries supplying the brain can be used to detect and follow diseases such as atherosclerosis, vascular narrowing and vascular occlusion. It can also be used to monitor the effectiveness of therapies such as vessel dilatation (angioplasty) or vascular stenting.
The test is safe and non-invasive, there are no side effects and it is painless. The results are most often used in combination with other tests to make an accurate diagnosis and plan appropriate treatment.
