Diffusion tensor imaging or diffusion weighted imaging
was used to study the tissue orientation and the
diffusivity properties. However, the long scan time for
applying different diffusion gradient in diffusion
weighted imaginglimit the clinical application in spine,
especially high resolutionimaging and 3D modeling. In
this study, we applied the accelerated technique single
carrier Wideband MRI with W=5acceleration on the 3D rat
spine diffusion study. The results demonstrated the
capacity to acquire 3D DTI imaging on rat spine by using
Wideband MRI technique, it also reduced the scan time
from 22.5 hours to 4.5 hours. We are looking into higher
acceleration rate and higher imaging resolution of rat
spinal diffusion study, and implementing on the clinical
study in the near future.
