Susceptibility Imaging can be useful for assessing
structural integrity in the spinal cord, which plays an
important role in many neurological disorders.1 However,
physiological noise from respiration causes artifacts in
in-vivo images. This phenomenon is particularly evident
in the Cervical-spinal (C-spine) cord because the
distance between the C-spine and the lungs is closer
than other regions 2. In order to characterize and
correct these respiration-induced artifacts of images,
navigator echo approaches have been widely used in
functional MRI, Diffusion Imaging etc 3 In this study,
B0 shift due to respiration is analyzed and this effect
is compensated using navigator echoes. Susceptibility
weighted image (SWI) of the C-spine is obtained using
the correction scheme.
