[Technique and diagnostic value of functional myelography in lumbar discopathy (author's transl)]

A standard myelogram using water soluble contrast with additional functional examination were carried out on 72 patients with suspected disc prolapse. Diagnostic accuracy can be significantly improved by the functional examination and, in some cases, the diagnosis can only be made in this way. There are no false positives. The advantages and limitations of the method are enumerated and its morphological significance is discussed.
