【摘要】 目的:探讨多层螺旋CT(MSCT)多平面重建(MPR)技术在胆石性肠梗阻诊断中的应用价值。方法:回顾性分析10例胆石性肠梗阻患者的影像学检查资料,所有患者均行16层螺旋CT扫描并通过AW4.3工作站对扫描数据进行MPR。结果:10例患者MSCT均显示肠梗阻征象,其中胆管积气7例,胆囊积气8例,胆囊窝结构紊乱10例。8例MPR明确显示胆囊十二指肠瘘,瘘口直径0.6~2.3 cm,平均(1.3±0.4)cm。异位结石13枚:7枚位于回肠,3枚位于空肠,2枚位于胃,1枚位于十二指肠,其中2例为多发结石;结石直径0.8~4.3 cm,平均(3.2±1.2)cm。结论:MSCT结合MPR技术可快速明确诊断胆石性肠梗阻,为临床治疗提供丰富全面的影像学信息,是目前诊断胆石性肠梗阻的首选检查方法。更多还原

【Abstract】 Objective: To assess the value of multi-planar reconstruction( MPR) imaging using multi-slice spiral CT( MSCT) in the diagnosis of gallstone ileus. Methods: The imaging data were reviewed in 10 cases of gallstone ileus. All patients underwent scans of 16-slice spiral CT,and the MPR was performed with AW4. 3 workstation. Results: Intestinal obstruction was detected in all 10 patients. Pneumobilia was observed in 7 patients,pneumo-gallbladder in 8,and structural disorder of gallbladder fossa in 10. MPR indicated obvious gallbladder-duodenal fistulas in 8 patients,with fistula diameter between 0. 6 and 2. 3 cm[mean( 1. 3 ± 0. 4) cm]. Totally,13 ectopic stones were detected,where 7 stones were found in ileum,3 in jejunum,2 in stomach,and 1 in duodenum. Multiple stones occurred in 2 patients,with a stone diameter ranging from 0. 8 to 4. 3 cm[mean( 3. 2 ± 1. 2) cm) ]. Conclusion: MSCT with MPR technique can make quick and clear diagnosis of gallstone ileus,and provide rich and comprehensive imaging information for clinical therapy strategy. This technique must be prioritized option for diagnosis of gallstone ileus.更多还原
