Keywords: Blood vessels, Velocity & Flow, High-Field MRI, AneurysmWe investigated relationships between unruptured intracranial aneurysm (UIA) morphology and hemodynamics parameters measured with 7T 4D flow imaging in 35 patients with an UIA. Blood flow measured in the UIA was positively correlated with UIA size, and negatively correlated with elongation and shape index of UIA (a decrease in shape index is characteristic for unstable UIA (either growing or rupture)). Therefore, blood flow is an important parameter for risk evaluation of UIA. The described relations help toobtain better insight in risk parameters of UIA development, growth, and possible rupture.
