We implemented RS-EPI DTI on 10 volunteers at 3T MR scanner with 32-channel head coil, and evaluated the feasibility of clinical application by analyzing trace, FA and color map images. RS-EPI has much higher spatial resolution compared with SS-EPI and can be a potential to be an alternative to SS-EPI DTI for evaluating the whole brain.
