Optimal computed-tomographic techniques for cervical spine imaging.

Abstract
Various techniques for optimal computed-tomographic imaging of the [human] cervical spine are compared. No single method is adequate for visualizing all anatomic structures. Thin sections are needed to obtain images of intervertebral disks, but thick sections are preferred to obtain images of the spinal cord. Spatial resolution is more important than contrast resolution when imaging the vertebrae. Small-body calibration is recommended for adequate cervical spine visualization, although some artifacts can be minimized when large-body calibration is used.
