Lumbar tomomyelography with water-soluble contrast medium.

Myelography supplemented by tomography was routinely carried out in 150 cases. The number of false negative findings was reduced practically to nil. At present, this method is only used in cases with equivocal results at conventional myelography or with poor correlation between clinical symptomatology and myelography. The frequency of side effects in 500 examinations with Dimer-X is unimportant.
