Lumbar myelography was performed in 50 patients; 25 received iohexol (an investigational aqueous contrast agent) and 25 received metrizamide. The two media produced radiographs of equal quality. However, iohexol is stable in solution, while metrizamide is not. Further, markedly less morbidity resulted from iohexol. These features indicate that iohexol may be superior to metrizamide as a contras...

BACKGROUND The authors describe a new computerized tomography (CT) myelography technique with coronal and oblique coronal view to demonstrate the status of the cervical nerve rootlets involved in brachial plexus injury. They discuss the value of this technique for diagnosis of nerve root avulsion compared with CT myelography with axial view. METHODS CT myelography was performed with penetrati...

We describe a rare complication of myelography. A subarachnoid filling defect was apparent on the postmyelographic CT but not on conventional myelography. MR imaging performed later showed a spinal subarachnoid hematoma (SSAH), extending from L3 to L5. Lumbar puncture may rarely be a cause for SSAH and is more common in patients with coagulopathy. Significant back pain, paresis, radiculopathy, ...

Serious adverse reactions after myelography with non ionic contrast media are relatively rare. No cases of encephalopathy and only one of seizure have been reported with intrathecal iopamidol. We describe two patients who had a seizure after iopamidol myelography in a retrospective series of 236 consecutive patients between April 1986 and September 1987 to emphasize that serious reactions to in...

Two hundred patients who underwent myelography with iopamidol were independently assessed as to film quality and adverse side effects. Comparison was made with a similarly assessed group of 1,000 patients who underwent myelography with metrizamide. Diagnostic quality was generally excellent with both contrast media. The incidence of side effects, notably vomiting and headache, was significantly...

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...

Since the introduction of the water-soluble contrast agent metrizamide, reports of side effects in man following myelography have been limited to the frequent occurrence of relatively minor symptoms such as headache and vomiting , and the occasional episode of grand mal convulsions [17]. Such convulsions may relate to an excessive quantity of the contrast agent spilling over the convexity of th...
