Abstract

Morbidity and mortality rates of stroke in Poland are the highest among developed countries. Better survival can be achieved if preventive treatment is timely implemented. Asymptomatic carotid artery stenosis contributes to a large proportion of strokes. Also, the narrowing of major intracranial cerebral arteries, predominantly caused by subarachnoid haemorrhage-induced vasospasm contributes to morbidity and mortality. Early detection and quantification of the narrowing is crucial for implementing the preventive treatment, however, there is an unmet need for an efficient diagnostic approach. In this seminar, I will overview the methodology of transcranial colour-coded duplex sonography in combination with carotid ultrasound that can be used to detect and quantify cerebral artery narrowing. We will discuss the potential use of artificial intelligence methods to integrate sonographic data from multiple arteries to improve classification accuracy.
