2D Time-Resolved Phase-Contrast MRI Measurements in Silicone Intracranial Aneurysm Phantoms (original) (raw)

Abstract

Aneurysm is widely believed as a fatal pathology. As one type of aneurysms, an intracranial aneurysm is notably dangerous due to its thin vessel wall and high rate of rupture. The objective of this study in vitro is to analyze the hemodynamics in an intracranial aneurysm using a silicone phantom. The feasibility of the phantom is verified. In order to visualize and quantify the flow in the phantom, time-resolved 2-dimensional phase-contrast MRI sequence is applied. With post-processing of images, velocity profile and 3-dimensional path lines are obtained and analyzed.
