摘　　要：目的:探讨16层螺旋CT多期增强扫描及图像重建在胆囊癌诊断中的价值。方法:对照病理,回顾分析25例胆囊癌多期增强扫描及各期图像重建的CT表现。结果:胆囊癌的强化特点为动脉期高密度、门脉期呈等密度或高密度、延迟期消退不明显,即胆囊癌的多期增强强化程度高于正常胆囊壁和肝脏,且强化时值延长。结论:胆囊癌的多层螺旋CT多期强化特征及不同的重建图像对胆囊癌的诊断及鉴别诊断有重要价值。Objective： To explore the value of 16 - stice spiral CT scan and reconstruction in the diagnosis of gallbladder carcinoma. Methods： The CT finding of 25 cases with pathologically provened gallbladder carcinoma were retrospective and analysed. Results： The gall bladder carcinoma had certain enhancing characteristics high density in hepatic artery period, same or high density in porch vein period, and no clear fadeaw ay in delaying period in otherwords, the gallbladder carcinoma was higher enhacem ent than normal gallbladder wall and liver, and had long term enhancem ent. Conclusion： The muhiphasic and recmstruction multishce spiral CT （MSCT） scan plays an important role in diagnosis and differential dingnosis of gallblader carcinoma.
