摘要目的：探讨低张水灌肠螺旋CT增强扫描对结肠癌临床分期的诊断价值。方法：选择2011年9月至2016年2月经肠镜活检病理证实为结肠癌患者78例，对低张水灌肠螺旋CT增强扫描的效果、特征、TNM分期进行分析。结果：所有患者都完成低张水灌肠螺旋CT增强扫描，病变区肠管充盈较好，平扫CT值为（35.42±11.63）HU，增强扫描动脉期为（76.33±12.72）HU，门脉期为（79.43±9.54）HU，平衡期为（80.14± 8.11）HU。低张水灌肠螺旋CT增强扫描病例全部检出；经过判定，CT对结肠癌T分期的准确性为84.6%，对N分期的准确性为82.1%，对M分期的准确性为97.4%。结论：低张水灌肠螺旋CT增强扫描在结肠癌中的应用具有很好的可行性与有效性，可提高术前TNM分期的准确性，有很好的应用价值。

Abstract：Objective: To explore the diagnostic values of hypotonic water enema spiral CT enhanced scanning on clinical staging of colon cancer. Methods: From September 2011 to February 2016, 78 colonoscopy and biopsy confirmed colon cancer patients in our hospital were selected, the result of the hypotonic water enema spiral CT enhanced scanning, characteristics and TNM stage were analyzed. Results: Hypotonic water enema spiral CT scan were completed in all patients, the lesion was filling good, the plain CT value was (35.42±11.63) HU, the arterial phase enhanced scan value was (76.33±12.72) HU, and the portal phase, the equilibrium phase enhanced scan value were (79.43±9.54) HU and (80.14±8.11) HU. All the patients were detected by the hypotonic water enema spiral CT enhanced scan; After determination, the accuracy of CT for colon cancer T staging was 84.6%, the accuracy of N staging was 82.1%, the accuracy of M staging was 97.4%. Conclusion: The application of hypotonic water enema spiral CT enhanced scanning in colon cancer has good feasibility and effectiveness, and it can improve the accuracy of preoperative TNM staging, and it has good application values.

Key words： hypotonic water enema tomography, spiral computed enhanced scan colon neoplasms TNM staging
