Peter Glass %A Sidney Wallace %T Myelography in Cancer Patients: Modified Technique %D 1985 %J American Journal of Neuroradiology %P 617-621 %V 6 %N 4 %X Because of the frequency of multiple sites of involvement, a thorough evaluation of the entire spinal canal is essential for detection and treatment of spinal compression in cancer patients. For the examination of the entire spinal canal in cancer patients, a modified approach is described using water-soluble contrast medium (metrizamide), oil-based material (Pantopaque), and a “squeezing” technique for a complete myelographic block. Of 240 patients who underwent myelography for possible spinal compression, the squeezing technique was applied through a lumbar puncture to demonstrate a complete block in 39 patients; six of these had more than one block. Of the other 201 patients, the quality of the myelograms was satisfactory or excellent in 189 (94%). %U https://www.ajnr.org/content/ajnr/6/4/617.full.pdf
