ABSTRACT
The article contributes to establishing direct correlative interchanges between MRA and ultrasonic diagnostics data on cerebral arteries perfusion (CAP) in terms of lowering CAP by cerebro-vascular insufficiency type. The data obtained by means of pathomorphological and pathohistological analyses on arterial and venous angioarchitecture, mathematical models of features of vessels branching "geometry" with possible reaction of the vessels to intravascular blood pressure changes, all this can explain variety of trigger zones causing ischemic lesions formation occurred by disgemias of different origins. The issue on cerebral arteries visualization demands from researches to develop more sophisticated methods of MRA to get high resolution ratio and obtain more detailed information about distant segments of cerebral arteries.
