An effective k-space undersampling scheme for 3D
Cartesian acquisition combined with compressed sensing
and parallel imaging has successfully been implemented
and applied to intracranial 4D flow MRI. Our preliminary
results demonstrated that the proposed approach achieved
high image quality and accurate velocity imaging with
largely accelerated acquisition (R=7).
