Computed tomography of the spinal canal and cord

Selective cases have been presented to demonstrate the usefulness of computed tomography in disorders of the spine and spinal cord. The osseous structures are more readily demonstrated than the soft tissues. The cord is difficult and inconsistently identified. However, cystic lesions (syringomyelia) may, at times, be demonstrated. The transverse projection of the CT scan is an added benefit in demonstrating bony spinal lesions. The use of metrizamide with faster scanners should improve the usefulness of this technique in evaluating intraspinal lesions.
