Clinical DTI in the cervical spine (C-spine) employs the
single shot EPI-based Diffusion Weighted Imaging (SS-EPI-DWI)
technique. Given the propensity for image distortion and
low signal to noise ratio, optimization of DTI image
quality often requires an increase in the number of
averages, at the cost of proportionally increasing scan
time. A modified SS-EPI-DWI sequence called
Slice-Accelerated-Single-Shot-Spin-Echo- EPI (commonly
termed as Multiband-DWI) offers improved image quality
while reducing scan time and image distortion. In this
study, we will evaluate C-spine image acquisitions at 3T
using Multiband-DWI and SS-EPI-DWI techniques,
specifically comparing 1) qualitative image quality, 2)
quantitative DWI/DTI metrics, and 3) acquisition scan
time.
