The Computed tomography is useful in evaluation of bony structures and adjacent soft tissues of the lumbar spine. Recently, the multiplanar recontruction of lumbar spine CT of significant value for the anatomical localization and for the myelographic and surgical correlation. We observed 177 Cases of lumbar spine CT, who complains of spinal symptom. during the period from Dec. 1982 to Aug. 1984 The results were as follows: 1. The sex distribution of cases were 133 males and 44 females. The CT diagnosis showed 152 cases of herniated lumbar disc, 15 cases of degenerative disease, 5 cases of spine tbc., 3 cases of spine trauma and 2 cases of meningocele. 2. CT findings of herniated disc were as follows: focal protrusion of posterior disc margin and obliteration of anterior epidural fat in all cases, indentation on dural sac in 92 cases (60.5%) soft tissue mass in epidural fat in 85 cases (55.9%) compression or displacement of nerve root sheath in 22 cases (14.4%) 3. Sites of herniated lumbar disc were at L4-L5 level in 100 cases (59.1%) and at L4-S1 level in 65 cases (38.4%) Location of it were central type in 70 cases (41.4%) left-central type in 46 cases (27.2%), right-central type in 44 cases (26.0%) and lateral type in 9 cases (5.1%) 4. The sagittal reconstruction images were helpful in evaluating neural foramina, size of disc bluge into spinal canal, expecially at L5-S1, and patients with spondylolisthesis. The coronal reconstruction images were the least informative, although they contributed to the evaluation of lumbar nerve roots of course, the axial CT scans were the sensitive and specific.
