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 12-year-old, castrated male Maltese dog was presented due to a sudden onset of tetraparesis. A ventral, extradural compressive lesion at the C4-5 intervertebral disk space, most compatible with an intervertebral disk extrusion was found by radiography, myelography and computed tomography. The dog received ventral slot surgery for cervical intervertebral disk hernia. After the surgery, the dog...

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...

This is a preliminary report of the first clinical trials using iohexol as a contrast agent in lumbar myelography. The study was noncomparative and involved 82 adult patients in four centers. Iohexol doses of 10-15 ml (180 mg I/ml) were administered and clinical and laboratory tests were performed before and at intervals during 48 hr after myelography. Side effects were noted in 29 (35%) of 82 ...

INTRODUCTION It is well-known that many patients will have adverse reactions such as headache and nausea after undergoing myelography, but we have often seen cases where symptoms such as lower back pain and leg pain were alleviated following myelography. To the best of our knowledge, such clinical cases of post-myelographic alleviation have not been reported. MATERIALS AND METHODS A total of ...

Computed tomographic (CT) measurements of the thoracic spine and its contents were obtained in 33 patients undergoing metrizamide myelography for various spinal disorders. Twenty-eight of these patients had symptoms referable to the cervical or lumbar region and form the basis of this study. Five patients had symptoms referable to the thoracic spine. Sagittal and coronal CT measurements of the ...
