High-resolution, cross-sectional computed tomography of the normal spine

CT has proved to be an excellent method of studying the spine in cross section. The osseous axial skeleton may be imaged without the need for contrast media. Analysis of the contents of the spinal canal requires administration of intrathecal contrast material, except in the lumbar region, where epidural fat serves as a natural contrast agent. This article illustrates and discusses normal axial CT anatomy of the spine.
