【摘 要】目的：本成果主要探讨胰胆管十二指肠连接区(PDDU)癌的病理、CT表现特点与扫描方法。方法：对52例经病理证实的PDDU癌的临床及CT图像资料进行回顾性分析。结果：螺旋CT诊断PDDU癌47例(乳头型32例，管腔内型13例，混合型2例)；主要表现为软组织肿块，十二指肠腔内充盈缺损及局部粘膜破坏和肝内外胆管、胰管、胆总管扩张；5例因扫描方法不当致漏诊、误诊。结论：螺旋CT能清晰显示PDDU癌的直接与间接征象，是一种很好的无创伤性检查方法，但正确的扫描方法是提高诊断率的前提条件。

    【Abstract】Objective ：To study the features of anatomy,pathology and CT findings in carcinomas at pancreaticobiliary ductal and duodenal union(PDDU). Methods：CT features of 52 cases were retrospectively studyed and correlated with their pathological characteristics. Results：Among 47 cases studied(32 were papilloma,13 were ductal type,and 2were mixed types);CT featuresduct and pancreatic duct.5cases missed or misdiagnosis for inappropriate scanning method. Conclusion：CT is one of noninvasivetesting methods,which can clearly display the direct and indirect signs of PDDU.But correctly scanning is prerequisite to increasing diagnosis preciseness. ......
