Diffusion-Weighted (DW) PROPELLER is a DW MRI acquisition method that is free from the EPI-related artifacts (e.g. image distortion) and has integrated motion correction scheme. However, the practicality of DW PROPELLER MRI is hindered from its markedly long scan time. In the present work, a novel DW PROPELLER MRI scan time reduction method using k-space undersampling with Fast RIGR (Reduced-encoding Imaging by Generalized-series Reconstruction) algorithm is presented.
