This
study demonstrates that single-shot spiral sampling can be adopted to acquire whole-brain diffusion tensor imaging
with shorter TE and higher SNR. In addition, the in vivo results show that single-shot
spiral DWI provides
accurate DTI metrics, and has high anatomical accuracy.

isotropic resolution using single-shot spiral sampling. (a) b0 (T2W) images.

maps.

slices covering the whole brain. The results indicate that single-shot spiral
diffusion imaging can provide accurate DTI metrics.
