WebbCase Discussion. This young patient with normal carotids had a TIA, and was found to have a non-occlusive thrombus in the M1 segment on the left. MRI and CT perfusion demonstrate no infarction, but mildly increased mean transit time. FLAIR nicely demonstrates high signal due to slow flow. WebbIn this study, image-based computational fluid dynamics (CFD) models were used to simulate the flow in four basilar artery aneurysms in order to evaluate postoperative hemodynamics that would result from flow-altering interventions. Patient-specific geometries were constructed using MR angiography and velocimetry data.
