[Present possibilities of ultrasonic diagnosis of intracranial cerebral vasculature].

The purpose of the submitted paper is to inform the wider medical public on a new non-invasive ultrasonic method for the examination of intracranial portions of the cerebral arteries. It is three-dimensional transcranial dopplerometry introduced for the first time in Czechoslovakia. The apparatus, Trans-scan 3-D of EME, makes it possible to obtain so-called ultrasonic arteriograms-scans of the basal arteries of the circle of Willis in all three projections with concurrent aimed analysis of flow parameters in real time. The results of this examination correlate significantly with angiographic findings. It is a risk-free method which does not cause discomfort to the patient and makes any number of repeated examinations possible. It is useful for the detection of pathological intracranial vascular conditions.
