An intuitive phase correction approach, SENSE+CG, has been proposed and implemented on navigator-free spiral DWI.In this study, regularization was introduced into the SENSE+CG algorithm to solve the semi-convergence problem. The in vivo results show that it can generate diffusion weighted images with fast and stable convergence, which is helpful to determine the stopping criterion without manual intervention.
