Computerized axial tomography in the diagnosis of lumbar disc hernia

Computerized axial tomography (C.A.T.) is a very useful method of investigation in the diagnosis of lumbar disc hernia. There is a high correlation with the operative findings and a very low incidence of false positives and negatives. The fact that it is a non invasive method extends its applicability to the evaluation and control of treatment, whether conservative, chemonucleolysis, or surgical, particularly in the present day medico-legal aspects of this syndrome.
