Colour-coded ultrasound of the blood vessels of the head and neck with a dopplerograph is a non-invasive and painless method to assess the condition of blood vessels, for instance, detect various congenital developmental characteristics (small diameter of blood vessels, curves and loops of blood vessels, additional branches of blood vessels) and blood vessel changes acquired during life (thickening of arterial wall, atherosclerotic plaque, atherosclerotic blood vessel constrictions or blocking of blood vessels).
The aforementioned acquired changes increase the probability of a stroke, therefore early diagnosis and treatment thereof is important (under the supervision of a cardiologist, neurologist, general practitioner or vascular surgeon).
It is important to understand that comprehensive evaluation of brain circulation requires an examination of blood vessels of the head, as well as neck. Significant changes are frequently found in the blood vessels of the neck, which further on branch to ensure the blood supply to the brain.
The changes detected during the examination may require further, more detailed examinations by using so-called angiography methods (CTA, MRA, DSA). Contrast agents and X-Ray radiation or magnetic fields are used to conduct these examinations.
