螺旋CT对诊断乏特氏壶腹癌的应用

Spiral CT in Diagnosis and Application of Carcinoma of Vaters Ampulla

目的:探讨螺旋CT在诊断乏特氏壶腹癌的应用价值。方法:回顾性分析了26例经手术病理证实的乏特氏壶腹癌的螺旋CT表现,均服开水做对比剂充盈肠管,病变局部采用薄层增强扫描,17例辅以图像后处理技术。结果:26例患者均有不同程度的胆道系统低位梗阻,25例CT图像能明确壶腹部肿块,能清晰显示肿瘤的部位,大小以及周围组织结构的关系。结论:壶腹部肿块是乏特氏壶腹癌的CT直接征象,应用螺旋CT薄层增强扫描与图像后处理技术相结合对壶腹癌的诊断和鉴别诊断是可靠而有效的方法,并对其手术治疗提供重要的指导作用。

Objective.To evaluate CT diagnostic value of carcinoma of raters ampulla. Methods： SCT findings of 26 cases of Vaters ampullary carcinoma proved surgically and pathologically were analyzed retrospectively in taking water to make the contrast fulling intestine and the focus were scaned by the thin -slice enhancement partially,in which 17 examples were auxiliary by image post - processing technology. Result： The 26 examples patients all have the varying degree the biliary duct system low position obstruction. In which 25 examples CT image can be clear about the mass in the region of raters ampulla,and clearly display the spot, the size as well as periphery the organizational structure relations of the carcinoma. Conclusion： The direct CT signs of carcinoma of vaters ampulla is finding mass in the region of Vaters ampulla, and it is a reliable and effective method to diagnosis and the distinction diagnosis of ampullary Carcinoma with the combination of the spiral CT scanning of thin - slice and image post - processing technology, and it offers important guidance role to its operation treatment.
