64排螺旋CT扫描对结肠癌的诊断价值

The Diagnostic Value of 64-Row Spiral CT Scan of the Colon

目的:探讨64排螺旋CT扫描对结肠癌的诊断价值。方法:回顾性分析36例经手术或结肠镜病理证实的结肠癌患者的CT影像资料,观察肿瘤的部位、大小、形态、周围侵犯及远处转移情况,判断肿瘤分期。结果:36例患者中升结肠15例,横结肠7例,降结肠5例,乙状结肠9例。病变CT表现为病变段肠壁局限性不规则增厚或环形增厚,管腔内外软组织肿块,局部管腔不规则狭窄,增强扫描病变部位明显不均匀强化,可见周围浸润及转移征象。结论:64排螺旋CT扫描能够较准确地显示病变部位、与周围结构关系、有无邻近器官侵犯及有无远处转移,对结肠癌的诊断及分期有重要价值,为临床手术方案的制定提供可靠的依据。

Objective： To investigate the diagnostic value of 64-row spiral CT scan of colon cancer. Methods： CT images were retrospectively analyzed data of 36 patients with surgically or colonoscopy for colon cancer patients with pathologically confirmed, observed tumor location, size, shape, violations of the surrounding and distant metastasis, determine tumor staging. Results： 36 patients, 15 cases of ascending colon, transverse colon seven cases, five cases of descending colon, sigmoid nine cases. CT lesions showed irregular thickening of the limitations of the lesion segment or ring wall thickening, luminal internal and external soft tissue mass, localized irregular luminal stenosis, the lesion was significantly enhanced scan heterogeneous enhancement, visible signs of invasion and metastasis around. Conclusion： 64-row spiral CT scan can accurately display the lesion and its surrounding structure, with or without adjacent organ invasion and distant metastasis of colon cancer diagnosis and staging of great value for the development of clinical programs to provide reliable operation basis.
