Cervical myelography was performed by lateral C1-C2 puncture in 60 patients. Thirty patients received iohexol (an investigational aqueous contrast agent) and 30 received metrizamide in order to provide a prospective, randomized, double-blind trial comparing these contrast media. The two media produced radiographs of equal quality. Contrast-related morbidity was suffered by four patients (13%) i...

BACKGROUND Conventional magnetic resonance imaging (MRI) of complex cervical spine disorders may underestimate the magnitude of structural disease because imaging is performed in a nondynamic non-weight-bearing manner. Myelography provides additional information but requires an invasive procedure. METHODS This was a prospective review of the first 20 upright weight-bearing cervical MRI proced...

An 8-year-old Warmblood gelding presented with a history of progressive ataxia for 6 weeks. Intra- and intervertebral ratios measured from lateral radiographs the cervical spine were within normal limits. Computed tomographic myelography revealed focal compression dorsal ventral contrast column as well displacement spinal cord canal due to bulging soft tissue attenuating material in half juncti...

Metrizamide myelography and postmyelographic computed tomography (CT) were evaluated for relative efficacy when correlated with operative findings in a series of 30 patients. Fifty-seven levels were operated on in the 30 patients with 27 patients diagnosed as having diffuse cervical stenosis, hyperostotic spondylosis, or herniated nucleus pulposus. Metrizamide myelography and CT metrizamide mye...

Cerebrospinal fluid-borne metastases were demonstrated by metrizamide myelography in 20 children with primary intracranial tumors, posterior fossa medulloblastomas being the most common. The lumbosacral region was affected most often, with nerve root thickening, nodularity, and irregularity of the thecal sac. Cord cloaking, nodularity, and meningeal disease were common in the cervical and thora...

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 wit...
