Thirty-two patients with lumbar disk herniation were studied by comparing MRI with X-P, myelography, CTM, so as to clear part of MRI in lumbar disk herniation. The results in this study proved well the value of MRI. We think that we can take operative steps by MRI only, if MRI findings are in accord with neurological findings, except for cases with MRI findings of multiple disk herniations.
