目的:探讨CT对直肠癌的诊断价值和CT表现。方法:收集和总结2000~2006年5月期间经纤维肠镜和(或)手术病理证实为直肠癌的10例病例资料与CT检查进行回顾性分析。结果:CT显示肿瘤部位的准确性为100%,CT可见癌变部位肠壁增厚、僵硬、肠腔狭窄,Ⅲ期以上直肠癌尚可见邻近器官侵犯、淋巴结肿大等。结论:CT在直肠癌的诊断中占有重要地位,不仅能够发现和显示病变,确定病变侵犯的范围及转移情况,更对确定肿瘤术前分期,选择治疗方法及判断预后起着重要作用。
Objective: To investigate the diagnostic value and CT appearance of CT in rectal cancer. Methods: Ten cases of colorectal cancer confirmed by fibro-colonoscopy and / or pathology during 2000 ~ 2006 were collected and analyzed retrospectively. Results: CT showed that the accuracy of the tumor site was 100%. CT showed thickening of the intestinal wall in the canceration site, stiffening, stenosis of the intestine, and adjacent organ invasion and lymph node enlargement in the stage Ⅲ or more rectal cancer. Conclusion: CT plays an important role in the diagnosis of rectal cancer. It not only can detect and display the lesion, but also determine the scope and metastasis of the lesion, and plays an important role in determining the preoperative staging, selecting treatment and prognosis.
