目的：通过研究脊髓纵裂的ＣＴ影像与手术所见的关系，评价ＣＴ扫描的诊断价值，揭示ＣＴ扫描在手术治疗、提高手术疗效及神经缺陷发生机制中的重要作用。方法：根据ＣＴ扫描影像与手术中所见的病理改变，对２３例进行对比研究。结果：根据ＣＴ影像与手术所见将脊髓纵裂间隔分为骨性、软骨性、纤维性和混合性。２０例患儿２３处脊髓纵裂中，骨性１８例，软骨性２例，纤维性１例，混合性２例，除１例纤维性间隔ＣＴ平扫未能显示外，其余的ＣＴ影像与手术所见相符。结论：ＣＴ平扫影像与手术中所见相符。ＣＴ扫描是脊髓纵裂理想的、有价值的诊断手段，给临床提供了清晰的病变图像，为手术的正确操作奠定了良好的基础，为研究神经缺陷的发生机制提供了重要依据。
OBJECTIVE: To evaluate the diagnostic value of CT scan by studying the relationship between the CT images of the spinal cord and the surgical findings, and to reveal the important role of CT in the surgical treatment, surgical treatment and neurodegenerative mechanisms. Methods: According to the CT scan images and pathological changes seen in surgery, 23 cases were compared. Results: According to the CT images and surgical findings, the spinal cord longitudinal division was divided into bony, cartilaginous, fibrous and mixed. Twenty cases of spinal cord in 23 cases had 18 cases of bony fracture, 2 cases of cartilage, 1 case of fibrosis and 2 cases of mixed. In addition to 1 case of fibrous cyst CT scan failed to show, the other CT images The surgical findings match. Conclusions: CT scan images are consistent with the findings in surgery. CT scan is an ideal and valuable diagnostic tool for spinal longitudinal rupture, which provides a clear pathological image of the clinical and lays a good foundation for the correct operation of the operation, and provides an important basis for the study of the mechanism of nerve defects.
