目的：探讨低张水灌肠螺旋CT双期增强扫描对结肠癌术前TNM分期的准确性及临床应用价值。方法选择广东省阳春市人民医院2012年1月-2013年5月，有完整影像和病理资料的结肠癌患者62例，回顾性分析CT影像在肿瘤的部位、肠壁侵犯的深度范围、周围脂肪间隙的变化、淋巴结及远处器官转移等特点，并与手术及术后病理对照，分析低张水灌肠螺旋CT双期增强扫描对结肠癌术前TNM分期的准确性。结果低张水灌肠螺旋CT双期增强扫描对结肠癌T分期准确率90．32％（56/62）， N分期准确率80．64％（50/62），M分期准确率100％（62/62）。结论低张水灌肠螺旋CT双期增强扫描能准确显示结肠癌的部位、确定肿瘤侵犯的深度范围、淋巴结和远处器官转移，更准确的诊断结肠癌和术前分期评估，可以作为结肠癌术前的首选检查方法。

Objective This paper is mainly to discuss accuracy and clinical application value of MDCT double-period enhanced scanning with low -tension water enteroclysis for colon cancer preoperative TNM stag-ing.Methods Sixty-two colon cancer patients with complete images and pathological data were selected in our hospital from January 2012 to May 2013 .We retrospectively analyzed CT image changes of the tumor location ,the extent of tumor invasion,the surrounding fat space,lymph node metastasis and distant metastasis.We compared them with postoperative pathology to prove the accuracy of MDCT double -period enhanced scanning with low -tension water enteroclysis.Results The results showed that its accuracy rate reached to 90.32%(56/62)in co-lon cancer preoperative Stage T,80.64%(50/62)in Stage N,and 100%(62/62)in Stage M respectively.Con-clusions MDCT double-period enhanced scanning with low -tension water enteroclysis can accurately display the site of colon cancer and determine the scope of tumor invasion ,lymph node metastasis and distant metastasis , and give more precise diagnosis of colon cancer and preoperative staging assessments .In conclusion , it can be used as the preferable method of preoperative examination in the colon cancer .
