Metrizamide in selective cervical myelography

The various techniques of cervical myelography are discussed and a technique is described to examine the cervical region after lumbar injection of the contrast medium. This technique is considered less hazardous than other techniques including application of the contrast medium by direct puncture in the cervical region and is advocated for use in patients who have free circulation of CSF and who do not have marked deformity or marked rigidity of the spine.
