螺旋CT动态增强扫描对直肠癌分期诊断的应用价值

Applied value of multilayer dynamic CT Scan in the diagnosis and staging of rectal carcinoma

目的:探讨多层螺旋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直肠癌患者38例CT影像表现,统计直肠癌局部影像特点、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:38例患者中癌灶为腔内肿块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。所有病例术后病理对照符合率为81.5%(31/38)。结论:多层螺旋CT增强扫描对直肠癌的诊断、分期和术后病理的对照一致性较高,术前螺旋CT增强扫描为手术方式的选择具有指导意义,并具有较高的临床应用价值。

Objective：To evaluate the value of multilayer dynamic CT scan in the preoperative diagnosis and staging of rectal carcinoma.Methods： CT findings of a retrospective analysis of 38 cases with pathologically confirmed cancer, study characteristics of partial image, Adjacent tissue invasion and distant organ metastasis, And compared with postoperative pathology.Results：Intraluminal mass 15 cases, Intraluminal mass associated with of bowel wall thickening 12 cases, The a tumor breakthrough serosa layer and surrounding tissue invasion 7 cases; Tumor invasion of adjacent organs or with distant metastasis 4 cases; consistent rate compared with pathological was 81.5%（31/38）.Conclusion： Multilayer enhanced CT scan is well consistent rate in the diagnosis and staging of rectal cancer compared with pathologic staging, Preoperative contrast enhanced CT scanning have guiding significance for clinical choice of surgical approach, With higher value of clinical application.
