The radiological investigation of intramedullary spinal tumours.

The place of the various radiological techniques in the diagnosis of spinal cord tumours is described. With appropriate regard to the clinical picture, the choice of selective angiography. Metrizamide or Myodil myelography, and possible cyst puncture and endomyelogram, may be made with accuracy. Air myelography is less useful and less frequently employed. With these radiological aids, accurate localisation of tumour nodules for biopsy or excision is usually possible, and the necessity for long exploratory laminectomies avoided.
