No major studies have been reported for assessing the utility of DWI obtained by Fast Advanced Spin-Echo (FASE) with Deep Learning Reconstruction (DLR) for head and neck MR. We hypothesized that DWI obtained by FASE with DLR could improve the image quality with less deformation and better diagnostic performance as compared with DWI obtained by Echo-Planar Imaging (EPI) in head and neck MR. The purpose of this study was to compare the capability of DWI obtained by FASE and EPI sequences with and without DLR for image quality and diagnostic performance on DWI in patients suspected head and neck tumors.
