Diffusion-Weighted MR Imaging in Head and Neck Cancer: Comparison between Half-Fourier Acquired Single-Shot Turbo Spin-Echo and EPI Techniques

Abstract

Primary tumors and lymph nodes are more easily visualized on EPI-DWI compared with HASTE-DWI. EPI-DWI has geometric distortion, however, which has a negative effect on interobserver agreement of ADC values.
