[Comparative study of computed x-ray tomography and saccoradiculography in the diagnosis of early lumbar disk herniation. Apropos of 50 surgically-proven cases].

Comparison of diagnostic accuracy using the two methods showed scanner imaging to provide superior results, with confirmation of herniated disc in 90 p. 100 cases based on purely discal semiological features. Limitations of the method result from the absence of epidural fat (narrow lumbar canals). A new hierarchy of radiological explorations in resistant lumbosciatica is proposed.
