In order to achieve high resolution spine DTI, the
2D-navigated interleaved EPI combined with a proposed
reconstruction method, Shot Encoded Parallel-imaging
Technique (SEPARATE), is used in this study. Cervical
spine and lumbar spine DTI results show the improved
resolution and reduced distortion compared to the
single-shot EPI DTI. Furthermore, the proposed method is
less sensitive to the mismatch between image data and
navigator than the image domain phase correction.
