DW-MRI is an invaluable technique for the diagnosis of neurological disorders. ssEPI is time efficient but suffers from geometric distortions. DW-PROPELLER and its variants, including turboPROP, have been proposed for generating distortion-free images. This project proposes a new whole-blade acquisition mode with phase correction in reconstruction to increase the blade width and consequently reduce the scan time by a factor of ~2, relative to the original turboPROP. Furthermore, the increased blade width allows for robust motion correction, which was typically not performed in PROPELLER-based DWI. In vivo results demonstrate advantages over ssEPI, and recently released product msEPI and SPLICE-PROPELLER.
