| 目的 分析壶腹癌及壶腹周围癌多层螺旋CT(MSCT)特征，探讨MSCT对本病的诊断价值。方法 回顾性分析经手术病理或经十二指肠胰胆管造影(ERCP)活检确诊的35例壶腹癌或壶腹周围癌患者的CT表现。结果 35例均发现肿瘤，增强扫描肿瘤本身可见不同程度强化，其中16例经图像后处理，35例均清晰显示肿瘤及肿瘤与周围组织、血管的关系。结论 MSCT增强扫描与三维重建技术相结合能清晰地显示壶腹部肿瘤病变及其与周围结构的关系，对于壶腹癌及壶腹周围癌的手术治疗具有重要的指导作用。 |

| Objective To evaluate the application of multi-slice CT (MSCT) in the diagnosis of ampullary carcinoma and periampullary carcinoma. Methods The MSCT films of 35 cases of ampullary carcinoma or periampullary carcinoma that had been proved by pathology or ERCP biopsy were analyzed. Results On MSCT studies, tumors were found in the region of ampullary in 35 cases and were enhanced in different degrees post-administration of iodine contrast iv, 16 of them were reconstructed. All these cases were shown definitely with neighbor tissue and vessles. Conclusion Using enhanced MSCT scan with 3D reconstruction, the tumors in region of ampullary or periampullary and its relationships with neighborhood can be well displayed. MSCT plays an important role in guiding operation protocol. |
