[Why still use myelography in neurosurgery?].

Recently CT scan and NMR imaging have become diagnostic routine methods for spine lesions, while myelography is no longer the method of choice in most cases. From the experience of our clinic, however, there remain some neurosurgical indications, which will be the contents of this publication. We would like to give a review of the present literature. Still remaining indications are: 1. Traumatic nerve root lesions 2. Anomalies of lumbosacral nerve roots 3. Cervical disc herniation: anterior disc excision vs. posterior operation. 4. Stenosis of the spinal canal in more than 2 levels 5. Neurological deficit after trauma of the spine 6. Functional Myelography 7. Spinal arteriovenous malformations 3 Patients are presented in the crucial phase of diagnostic evaluation. Based on their outcome, the indications of myelography are discussed.
