Contrast-enhanced CT can be useful in differentiating between recurrent disk herniation and scar formation after disk surgery. Thirty such CT studies were assessed retrospectively to determine the utility of CT attenuation measurements in identifying intraspinal pathology. Measured values of intraspinal tissues, but also of "reference" materials such as CSF, blood, and muscle tissue, showed large individual variations; and enhancement patterns for recurrent herniation and scar formation were not specific. The chief value of contrast administration may lie in the clearer definition that is gained of various structures within the postoperative spine.
增强CT有助于鉴别椎间盘手术后复发性椎间盘突出和瘢痕形成。对30例此类CT研究进行回顾性评估，以确定CT衰减测量在识别椎管内病变中的效用。椎管内组织以及脑脊液、血液和肌肉组织等“参考”材料的测量值显示出较大的个体差异；复发性椎间盘突出和瘢痕形成的强化模式并不特异。注射造影剂的主要价值可能在于能更清晰地显示术后脊柱内的各种结构。
