Duplex Sonography of the Neck Vessels (Carotid Doppler)
Sonography of the carotid arteries consists on the one hand of determining the thickness of their inner walls (intima-media complex) and on the other hand of displaying the soft, hard, calcified or also shadow plaques in the vascular region of the extracranial brain vessels. The spread of the intima-media complex and plaques are signs of systemic arteriosclerosis. In connection with high cholesterol levels, high blood pressure, obesity, or nicotine abuse, sonography of the neck vessels thus offers important clues about your risk situation. Color-coded duplex sonography of the neck vessels displays serious constrictions, occlusions, vascular tears, or a reversed flow in the vertebral artery.
