An MRI examination for evaluation of aortic dissection using a blood-pool agent is presented. The aims of this study were to investigate the use of direct thrombus MRI and quantitative flow analysis for the determination of false lumen thrombus volumes in patients with Type B aortic dissection. It is shown that blood-pool imaging together with direct thrombus MRI allows assessment of aortic anatomy and more accurate quantification of false lumen thrombosis compared with CT. Current clinical trials using false lumen thrombosis as a primary endpoint should consider multi-parametric MRI as the preferred diagnostic tool.
