Diagnosis of CT and MRI in the Patients with Lumbar Disc Herniation

Objective:To analyze the CT and MRI findings in 191 cases with lumbar disc herniation. Method: 104 had CT examination. 87 had MRI examination 44 both had CT and MRI examination. Result:In CT group, lumbar disc herniation lie in Lumbar 3 to 4 has 12 case, lubmar 4 to 5 has 32 cases. Lumbar 5 to S1 has 60cases. 31with myelosis,11with calcification fo the herniated disc and 9 with calcification of the sagital ligament. In MRI group, 41 cases show the degeneration of disc. In the group which both have examination of CT and MRI show that CT has the menifestation of calcification of the herniated pulposus nucleus and sagital ligament, but MRI only shows the herniated of disc and extension of fat space be-for duralsac. Conclusion:CT is better to show the vertebral canal, myelosis, ossification, calcification of pulposus nucleus and ligament. Whereas MRI has the significant effects to show the degree and time of the prolapsing pulp nucleus.
