目的 :探讨低张结肠水灌肠CT检查对结肠癌的CT表现及诊断价值。材料和方法 :肌注 65 4 2 2 0mg后 ,结肠灌注微温生理盐水进行CT扫描。分析经手术病理证实的 3 8例结肠癌资料。结果 :CT显示肿瘤部位准确率为 10 0 % ,CT分期与手术分期符合率为 92 % ,低张结肠水灌肠CT可见病变肠壁增厚、突出腔内的肿块、肠腔狭窄及其浆膜面毛糙 ;可见结肠癌侵犯邻近器官、淋巴结肿大及远处转移。结论 :低张结肠水灌肠CT检查对结肠癌的术前诊断有很大的价值。
Objective: To investigate the CT findings and diagnostic value of low-tension colon water enema CT examination on colon cancer. Materials and Methods: After intramuscular injection of 654220mg, colon perfusion lukewarm saline for CT scan. Analysis of 38 cases of colon cancer confirmed by surgery and pathology. Results: The accuracy of CT was 100%, and the coincidence rate of CT staging and surgical staging was 92%. CT showed that the bowel wall was thickened, the cavity mass, the stenosis of the intestine and the serosa Surface rough; visible colon cancer invades the adjacent organs, lymph nodes and distant metastasis. Conclusion: Low-tension colon water enema CT examination of colon cancer preoperative diagnosis has great value.
