Towards high resolution 4D flow MRI in the human aorta using kt GRAPPA and B1+ shimming at 7T
To evaluate the feasibility of aortic 4D flow magnetic resonance imaging (MRI) at 7T with improved spatial resolution using kt GRAPPA acceleration while restricting acquisition time and to address radiofrequency (RF) excitation heterogeneities with B1+ shimming.
