Spine
• The CT scan following myelography must be per-
formed within 4 – 6 hours of the injection, other-
wise, the contrast density in the spinal canal will be
too high to obtain artifact-free images. Also, if possi-
ble, it is a good idea to roll the patient once, or scan
in a prone position. This will prevent the contrast
from pooling posterior to the spinal cord.
• If a prone scan is performed, breathing instructions
are recommended to avoid motion artifact in axial
source and MPR images.
• To further optimize MPR image quality, we recom-
mend that you reduce one or more of the following
parameters: collimation, reconstruction increment,
and slice width for image reconstruction.
