Compared to DW-EPI, DW PROPELLER is less sensitive to susceptibility, chemical shift, and motion, and thus shows better image quality in areas, such as skull base, head-neck and pelvis. However, the SNR and in-plane resolution of DW PROPELLER images are often inferior to DW-EPI and often requires a longer scan time to compensate for this. In this work, we evaluated a deep-learning reconstruction method to improve the SNR of in-plane resolution of DW PROPELLER images without increasing acquisition time.
