摘　　要：目的探讨多层CT增强扫描在直肠癌术前诊断、分期中的应用价值.方法回顾性分析经病理证实的38例直肠癌的CT影像表现,统计局部影像特点,邻近组织侵润情况及远处脏器转移情况,并与术后病理对照.结果癌灶为腔内肿块15例,腔内肿块伴有肠壁增厚12例,肿瘤突破浆膜层并周围组织侵犯7例;肿瘤侵犯邻近器官或伴有远处转移4例;与术后病理对照符合率为84.2%(32/38).结论多层CT增强扫描对直肠癌的诊断和分期与术后病理的对照一致性较高,因此术前CT增强扫描为临床手术方式的选择有指导意义,应用价值较高.Objective To investigate the value of dynamic enhanced multi-slice CT scan in the preoperative diagnosis and staging of rectal carcinoma.Methods CT imaging findings of 38 cases with pathologically confirmed cancer were conducted a retrospective analysis.The partial imaging characteristics,adjacent tissue invasion and distant organ metastasis were performed a statistical analysis and compared with postoperative pathology.Results Intraluminal mass was 15 cases,Intraluminal mass associated with of bowel wall thickening was 12 cases,a tumor breakthrough serosa layer and surrounding tissue invasion was 7 cases,and tumor invasion of adjacent organs or with distant metastasis was 4 cases.The consistent rate compared with pathology was 84.2%（32/38）.Conclusions Dynamic enhanced multi-slice CT scan existed fairly high consistency in the diagnosis and staging of rectal cancer compared with pathologic staging.It exhibited the guiding significance for clinical choice of surgical approach and higher value of clinical application.
