Value of computed tomographic myelography in the recognition of cervical herniated disk

Abstract

Three patients with cervical radicular symptoms and normal metrizamide myelograms underwent thin-section high-resolution computed tomographic scanning because of a strong clinical suspicion of herniated disk. Herniated disk was demonstrated in all three cases. In two, the disk protrusions were recognized only by computed tomographic myelography, and in the third case, the diagnosis was made with plain computed tomography and confirmed by computed tomographic myelography.
