The varied flow velocities and directions result in more rapid dephasing and signal loss termed "intravoxel dephasing." A commonly encountered CSF flow artifact is the signal void in the dorsal subarachnoid space on sagittal T2-weighted images of the thoracic spine (Fig.

For the thoracic spine, an axial 2D GE sequence is acceptable. FSE techniques are more difficult to use in the cervical and thoracic spine because of CSF pulsation artifacts. In the lumbar spine, an axial T2-weighted FSE sequence is opti-mal because CSF pulsation artifact is not a signif-icant problem.
