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.
