Demodulated balanced steady state free precession
(bSSFP) is employed to image the spinal cord at 3T. Four
phase cycled images are acquired from a cervical spine
patient, and a complex plane geometric solution is
exploited for elimination of dark bands and general
signal modulation. A complex average of the acquired
data shows reduced bands but uneven signal intensity in
the CSF, whereas the proposed solution yields
homogeneous CSF signal without banding such that the
spinal cord and epidural space are easier to visualize.
