Imaging diagnosis of myelography and CT-myelography in intervertebral disc hernia with operative correlation

Objective:To assess the value of myelography and CTM for the diagnosis of intervertebral disc hernia.Methods:Myelography and CTM scanning were performed in 200 patients with surgically proved intervertebral disc hernia.Results:The diagnosis accuracy of 45 cases single intervertebral disc hernia and 155 cases multiple intervertebral disc hernia,was 191 out of 200 by myelography(95.5%),200 out of 200 by CTM(100%)Conclusion:The location,direction,degree and section in intervertebral disc hernia are clearly demonstrated,myelography and CTM for the diagnosis of intervertebral disc hernia demonstrate high sensitivity,they can be used as modality for evaluating the therapeutic effect and the choice of operation,can be employed in routine diagnosis.
