Towards high-resolution 4D flow MRI in the human aorta using kt-GRAPPA and B1+ shimming at 7 tesla
PURPOSE: To evaluate the feasibility of aortic 4D flow MRI at 7T with improved spatial resolution using kt-GRAPPA acceleration while restricting acquisition time and to address RF excitation heterogeneities with B1+ shimming. MATERIALS AND METHODS: 4D flow MRI data were obtained in the aorta of 8 su...
