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.
