In this work a multishot 3D turbo spin echo (TSE) sequence is combined with a diffusion preparation module and a modified implementation of the cartesian spiral (CASPR) k-space sampling pattern. CASPR samples the center of k-space in each shot, providing redundancy and enabling self-navigated identification of corrupt data.
Using low resolution reconstructions per shot, weights are assigned for each shot enabling a soft-weighted compressed sense reconstruction.
Results are obtained in a phantom and healthy volunteers, demonstrating the feasibility in acquiring undistorted 3D diffusion images.
