PURPOSE To determine the sensitivity of contrast MR versus myelography followed by CT in the detection of cerebrospinal fluid metastases in children with primary central nervous system tumors. METHODS Thirty-three patients who had primary central nervous system malignancies had spinal MR with gadolinium within 2 weeks of a myelogram followed by CT. MR technique included T1-weighted image sequ...

Metrizamide, a water-soluble iodinated contrast agent for myelography, has been widely used in the United States for more than 4 years . Although acute generalized encephalopathy with confusion has been recog nized as a complication of metrizamide myelography, aphasia, with the connotation of focality that it entails, has seldom been reported [1, 2]. We describe two patients with a transient mo...

PURPOSE To report that iopamidol myelography can induce status epilepticus (SE) in patients carrying the diagnosis of symptomatic epilepsy and to estimate the incidence of seizures in patients undergoing iopamidol myelography. METHODS We retrospectively identified all patients with seizures/SE associated with 1350 iopamidol myelographies during the last 5 years at our institution. The impact ...

OBJECTIVES Although magnetic resonance imaging (MRI) is reported to be superior to myelography to determine the location and site of first time disc herniation, comparison of these diagnostic methods in cases of recurrent intervertebral disc disease (IVD) herniation after a first surgery has not been evaluated. The objective was to compare the diagnostic accuracy of MRI and myelography in a ser...

Computed tomographic (CT) myelography subsequent to nonionic water-soluble contrast medium myelography has provided additional diagnostic information for evaluating intraspinal mass lesions. In 20 patients thus studied, there were eight intramedullary tumors, eight intradural extramedullary masses, and four extradural neoplasms. In intramedullary tumors CT enabled more precise delineation of th...

Background. Intraoperative myelography has been reported for decompression control in multilevel lumbar disease. Cervical myelography is technically more challenging. Modern 3D fluoroscopy may provide a new opportunity supplying multiplanar images. This study was performed to determine the feasibility and image quality of intraoperative cervical myelography using a 3D fluoroscope. Methods. The ...

Digital subtraction myelography is described for its utility in the detection of dural leaks associated with pseudomeningoceles. Although myelography, CT, and MR imaging have been described as effective means for diagnosing pseudomeningocele, this complicated entity can be difficult to diagnose.

IN a significant number of cases of posterior prolapse of a lumbar intervertebral disc there is doubt as to the cause of symptoms and of the level affected. Contrast myelography is frequently used in this type of case in the hope that a more definite answer may be given. Reports on the accuracy of myelography in the diagnosis of prolapsed lumbar intervertebral disc vary between 67 per cent and ...

BACKGROUND AND PURPOSE We adopted an imaging algorithm in 2011 in which extradural fluid on spinal MR imaging directs dynamic CT myelography. We assessed algorithm compliance and its effectiveness in reducing repeat or unnecessary dynamic CT myelograms. MATERIALS AND METHODS CT myelograms for CSF leaks from January 2011 to September 2014 were reviewed. Patients with iatrogenic leaks, traumati...

A prospective, double-blind study was undertaken to assess the effectiveness of oral dexamethasone premedication in reducing a variety of side effects associated with metrizamide myelography. We also examined the relationship between side effects and needle size, total metrizamide dose, radiographic findings, and personality. Patients were randomly assigned to either a placebo group (44 patient...
