[Value of metrizamide myelography with tomodensitometry for study of the cervical spine]

52 metrizamide myelographies practiced with tomodensitometry were studies (23 normal cases); 6 cervicarthrosic myelopathies; 2 intra medullar tumors; 1 extra medullar tumor; 19 syringomyelias). The technical procedures are discussed for the different diseases. This test has proven highly interesting for the study of syringomyelias and tumors. It allows the presence of narrow canals to be demonstrated, but does not yet indicate discal hernias. The role of tomodensitometry, in relation to other exams, is demonstrated.
