In this study, we aimed to explore accelerated acquisition of multi-contrast 3D images with different magnetization preparation times. We combined shuffled acquisition in k-space, parallel imaging, compressed sensing and pixel-wise low rank Hankel matrix reconstruction, achieving reconstruction of tens of multi-contrast 3D images from three 3-minute scans.
