Computed tomography can accurately distinguish a bulging disc with intact annulus from a herniated nucleus pulposus in most patients. A bulging annulus should be diagnosed when CT scans demonstrate generalized extention of the disc margins beyond the adjacent vertebral body margins. A herniated nucleus may be diagnosed by a CT scan when there is focal protrusion of the disc margin beyond the vertebral body margins. However, correlation between clinical and CT findings remains a critical factor in determining the significance of an abnormality detected by a CT scan.
计算机断层扫描能够在大多数患者中准确区分椎间盘膨出（纤维环完整）和髓核突出。当CT扫描显示椎间盘边缘广泛延伸至相邻椎体边缘之外时，应诊断为椎间盘膨出。当椎间盘边缘有局灶性突出超出椎体边缘时，CT扫描可诊断为髓核突出。然而，临床与CT检查结果之间的相关性仍然是确定CT扫描所检测到异常的重要性的关键因素。
