Examinations of anomalies in the carotid arteries
Extracranial Doppler-sonography is employed for the examination of possible vasoconstrictions and vascular occlusions within the carotide arteries. It is a common diagnostic method for stroke prophylaxis and the clarification of circulatory disorders. For a full assessment of possible vascular disorders, extracranial Duplex-Sonograpy is the diagnostic method of choice, which combines Doppler-sonography with Color-Doppler imaging. This method, which is also known as Carotid Duplex, facilitates the visualization and measuring of the intima-media-thickness, the tracking of changes in arterial walls and diameters, and serves to make predictive statements on cardiovascular health risks. In addition, color-coded Doppler-technology visualizes the blood flow and measures the flow velocity within carotid arteries, which is higher in constricted blood vessels and in many cases a first sign for an increased stroke risk.
Like all ultrasound methods, Duplex-Sonography is non-invasive, painless, free of any radiation and thus completely safe for patients and examiners.
Applications for extracranial Duplex-sonography include:
