MRI Characteristics of Cerebral Venous Outflow
To study the nature of blood flow throughout cerebral venous structures in norm using MRI flow quantification technique Quantitative Flow. MRI studies were examined with modified 2D phase contrast magnetic resonance angiography retrospectively cardiac triggered Quantitative Flow technique. 64 healthy volunteers were investigated. Quantitative characteristics of the blood flow through intracranial venous sinuses and jugular veins describing a multilevel cerebral venous outflow. An attempt to estimate the influence on the blood flow to such factors as: vessel incline, the nature of blood flow, vascular wall structure and a cross-sectional area of vessels at intra- and extracranial level. Our findings show the importance of multimodality multilevel cerebral venous blood flow estimation and allows to look at this system as a single whole, with their relationships and influence laws.
