16层螺旋CT三维重建在胆道梗阻性疾病中的应用

The application of three dimensional reconstruction of 16 slice spiral CT in biliary obstructive disease

目的:探讨16层螺旋CT胆道三维重建在胆道梗阻性疾病的诊断及指导治疗方面的应用价值。方法:对26例梗阻性黄疸的患者行16层螺旋CT扫描,然后运用多平面重建(MPR)、曲面重建(CPR)进行定位、定性诊断,并与手术所见及病理结果进行对照分析。结果:26例患者中17例胆道结石,3例胆管癌、2例胰头癌、2例壶腹部癌、1例先天性胆总管囊肿、1例炎性肉芽肿。结论:16层螺旋CT胆道三维成像能够无创伤、立体清晰地显示胆管结构,对胆道梗阻性疾病诊断有非常重要的价值,并进一步指导临床手术治疗。

Objective ：To study the diagnosis and guiding treatment value of three dimensional reconstruction of 16 slice spiral CT in biliary obstructive disease. Methods： In 26 cases of obstructive jaundice patients of 16 slice spiral CT scan- ning, and then use multiplanar reconstruction （MPR）, surface reconstruction （CPR） localization, the qualitative diagno- sis, what could see in surgery and pathological results were compared. Results：Of 26 cases , 17 cases of biliary calculus, 3 cases of bile duct carcinoma, 2 cases of pancreatic head carcinoma, 2 cases of pot of abdominal carcinoma, 1 cases of congenital common bile duct cyst, 1 cases of inflammatory granuloma. Conclusion：Three dimensional reconstruction of 16 slice spiral CT imaging can clearly show bile duct structure of biliary obstructive diseases without trauma. It has a very important value, and further guide in diagnosis and surgery.
