We evaluated the feasibility of clinical application for Read-out Segmented (RS)-EPI DWI at 3T MR scanner with 32-channel head and neck coil, on both phantom study and patient study by comparing with conventional Single-Shot (SS)-EPI DWI. The RS-EPI DWI allowed a better identification of structure and provided less-distorted images than the SS-EPI DWI in head and neck area, whereas RS-EPI DWI yielded similar ADC value to SS-EPI DWI.
