DSC-MRI requires high temporal resolution to accurately measure perfusion parameters in vivo. Using GRAPPA parallel imaging, it is possible to achieve whole-brain coverage while maintaining high temporal sampling. The proposed method combines a 3D dual echo spiral sequence with through-time GRAPPA for whole-brain coverage with < 1 second temporal resolution.
