The purpose of this study is to observe the aortic root
vortex and to quantify vorticity in specific sites along
the aorta with usage of phase-contrast MRI so as to
realize the impact of vortical flow on the risk of
aortic dissection. In the velocity vector fields in left
ventricular outflow track view, the presence of vortical
flow at peak systole and the absence of vortices at end
systole may attribute to the dilated aortic root in MFS
patients. The quantified vorticity also showed decreased
values for MFS patients, particular in the sinotubular
junction.
