Computed tomography (CT) of the lumbar spine was performed with selectively positioned 5-mm-thick axial cross sections to examine each disk level from the top of the neural foramen to the pedicle of the next caudad vertebra. One hundred consecutive patients with 116 surgical disk explorations were reviewed. There was agreement between the CT and surgical findings in 89 patients (104 explorations) in determination of presence or absence of a herniated nucleus pulposus (HNP). Discrepancy occurred in 12 instances (11 patients): two because of incorrect interpretations, five in previously operated patients, three in spondylolisthesis, and two in spinal stenosis. There were 97 true-positives, eight false-negatives, seven true-negatives, and four false-positives. If nine previously operated patients are excluded from the study, then CT was accurate in detection of presence or absence of an HNP in 93% of the disk explorations.
腰椎计算机断层扫描（CT）采用选择性定位的5毫米厚轴向横截面进行，以检查从神经孔顶部到下一个尾侧椎体椎弓根的每个椎间盘水平。回顾了连续100例接受116次手术椎间盘探查的患者。在确定是否存在髓核突出（HNP）方面，89例患者（104次探查）的CT结果与手术结果一致。12例（11例患者）出现差异：2例是由于解读错误，5例发生在既往接受过手术的患者中，3例发生在腰椎滑脱患者中，2例发生在椎管狭窄患者中。有97例假阳性、8例假阴性、7例真阴性和4例假阳性。如果将9例既往接受过手术的患者排除在研究之外，那么在93%的椎间盘探查中，CT在检测HNP的存在与否方面是准确的。
