64层CT及三维重建技术对十二指肠乳头癌的诊断价值

Diagnostic Value of 64 Layer CT and Three-dimensional Reconstruction Technique in Duodenal Papillary Carcinoma

目的回顾性分析十二指肠乳头癌的64层CT表现,评价CT和三维重建技术对十二指肠乳突癌的诊断价值。方法回顾性分析经病理证实的21例十二指肠乳头癌的CT平扫、增强及三维重建像表现。结果 64层CT显示十二指肠乳头部结节肿块型11例、十二指肠管壁增厚型7例和胆总管及胰管壁增厚型3例;三维重建像显示胆总管突然截断4例,鸟嘴样狭窄3例,鼠尾状3例。结论 64层CT及三维重建技术对十二指肠乳头癌的诊断具有重要价值。

Objective Retrospective analysis the 64 layer CT performance of duodenal papillary carcinoma, and evaluation the diagnosis value of CT and three-dimensional of duodenal papilla cancer. Methods Retrospective analysis the performance of CT plain sweep, enhance and 3 d reconstruction of 21 patients with duodenal papillary carcinoma which been confirmed by pathology, Results The duodenal papilla departmeut nodular mass type in 11 cases, duodenal wall thickening type in 7 cases and common bile duct and pancreatic duct thickening type in 3 cases. Three dimensional reconstruction showed brav- ery manager sudden truncation in 4 cases, beak sample stenosis in 3 cases, rat caudate in 3 cases. Conclusion The diagnosis walue of 64 layer CT and three-dimensional reconstruc- tion technique is important to duodenal papillary carcinoma.
