Disease relevance of Myelography

• Asterixis after metrizamide myelography [1].
• In a case of chronic, severe urticaria and intermittent episodes of anaphylaxis due to an iophendylate injection (Pantopaque) given in the course of myelography, almost complete relief was obtained from the removal of approximately 8 ml of residual iophendylate from the spinal canal [2].
• Prolonged paraplegia after iohexol myelography [3].
• Complex partial status epilepticus following myelography with metrizamide [4].
• We describe 3 patients (from a series of 785) who had generalized tonic-clonic seizures after iopamidol myelography [5].

Psychiatry related information on Myelography

• The authors report a patient who developed an organic affective disorder with manic symptoms several hours after metrizamide myelography [6].
• Five patients examined with metrizamide (3%) experienced transient confusion and disorientation after lumbar myelography [7].
• Intracranial iohexol-distribution following cervical myelography, postmyelographic registration of adverse effects, psychometric assessment and electroencephalographic recording [8].
• Formed visual hallucinations after metrizamide myelography [9].
• The possibility of using psychologic tests to demonstrate psychic changes following myelography with metrizamide was investigated in 15 patients [10].

High impact information on Myelography

• Prolonged delirium after metrizamide myelography [11].
• An abnormal result for both tests thus indicates a sufficiently high probability of MS to exclude myelography, but a positive result in only one test warrants the procedure [12].
• Patients were staged postoperatively with contrast-enhanced cranial computed tomography, myelography, and CSF cytology [13].
• Seizures following myelography with iopamidol [5].
• Absence status epilepticus following metrizamide myelography was associated with computed tomographic scan evidence of a high concentration of the dye in brain gray matter [14].

Chemical compound and disease context of Myelography

• Thiamin, thiamin monophosphate, ascorbic acid, and folic acid were determined in serum and cerebrospinal fluid (CSF) in 31 outpatients who underwent a myelography because of back-pain [15].
• The effectiveness of prophylactic intrathecal methylprednisone (MP) in preventing arachnoiditis from iocarmate myelography was studied [16].
• Adhesive arachnoiditis, a meningioma and a schwannoma were found at autopsy in a 56 year old man who had undergone Thorotrast myelography 33 years previously [17].
• A case of Pantopaque pulmonary embolism during myelography is presented [18].
• Aseptic meningitis complicating iotrolan myelography [19].

Biological context of Myelography

• Pharmacokinetics and excretion of iohexol after lumbar myelography in man [20].
• Oil and metrizamide contrast myelography in the prone position were of limited value in diagnosing this condition; in fact, myelography may be misleading and result in erroneous diagnosis of thoracic disc protrusion, when the principal problem is dorsal and lateral compression from hypertrophied facets [21].
• The kinetics of iopamidol, a new nonionic radiocontrast agent, were evaluated in 10 patients undergoing lumbar myelography [22].
• In all patients, the results of the tests performed, including evoked potentials, CT scanning, oligoclonal bands in the CSF and myelography, were normal or inconclusive and did not lead to the correct diagnosis of the aetiology [23].
• Arterial blood pressure and heart rate were recorded for 5 to 7 h during myelography with iothalamate meglumine and metrizamide in 23 rabbits [24].

Anatomical context of Myelography

• Computed tomography of spinal cord after lumbar intrathecal introduction of metrizamide (computer-assisted myelography) [25].
• Introduction of metrizamide into the lumbar subarachnoid space with the patient in a prone 15-20 degree head-down position improves delivery of contrast material for cervical myelography [26].
• Thorough myelography of the entire spinal cord including the foramen magnum region can be accomplished consistently and promptly after metrizamide injection via lumbar or lateral cervical puncture [27].
• Iodine concentrations in serum and cisterna magna cerebrospinal fluid were studied in animals undergoing myelography with metrizamide, iocarmate, Iopamidol, or P-297 [28].
• Amipaque myelography without late adhesive arachnoid changes [29].

Associations of Myelography with chemical compounds

• Encephalopathy after iohexol myelography [30].
• Comparison of myelography with CT follow-up versus gadolinium MRI for subarachnoid metastatic disease in children [31].
• Indium scan, computed tomography (CT) scan, and myelography were helpful in diagnosis [32].
• This technique is reliable and offers advantages over Pantopaque and/or gas myelography [33].
• Thirty-eight patients underwent electroencephalography both before and after myelography (19 iotrol and 19 metrizamide) [34].

Gene context of Myelography

• OPLL was diagnosed on plain radiographs and cord compression ascertained by conventional and computer-assisted myelography [35].
• At myelography, samples of cerebrospinal fluid were drawn and later analyzed for neuropeptides vasoactive intestinal polypeptide and somatostatin [36].
• The myelography showed a complete block at T12 and the CT scan showed a mass at T11-T12 compressing the spinal cord [37].
• The tumor was detected at the level of T11 and L3 by myelography [38].
• Myelography showed an extrinsic compression of the dura sac at T10 [39].

Analytical, diagnostic and therapeutic context of Myelography

• In a prospective, randomized, double-blind study, 49 patients underwent lumbar myelography using iotrol (24 patients) or metrizamide (25 patients) [34].
• Using this method, we have determined reference intervals for amino acids, including GABA, in CSF in a group of pediatric patients who underwent lumbar puncture before myelography, and who were subsequently shown to have normal myelograms [40].
• Prospective comparison of epidural venography and iophendylate myelography in the diagnosis of herniated lumbar disks [41].
• All patients treated after 1974 had myelography and most had CSF cytology studies prior to radiotherapy [42].
• Three patients of the 25 examined with iopamidol showed EEG evidence of neuronal excitability following myelography [43].
