Computed tomography of lumbar disc herniation.

Abnormality of the bony structures of the spinal canal can be seen clearly with computed tomography (CT). Earlier utilization of CT to diagnose disc herniation was limited because of difficulty in obtaining a detailed image. Since 1978 we have used the General Electric CT/T-X2 scanner, and with this, disc abnormalities are clearly visible. In this paper, we demonstrate the findings and differences of lumbar disc abnormalities in operated and nonoperated cases.
