Abstract: 【Abstract】〓Objective〓To investigate the clinical effect of digital tomosynthesis on diagnosis of bile duct residual stone. Methods〓Thirty-one patients with hepatolithiasis were performed surgical treatment and stayed the biliary drainage tube after operation. All of patients received both abdomen digital radiography and digital radiography examination. The scores of DR and DTS imagines were analyzed the bile duct resident stones under the standard of choledochoscopy exploration. Results〓The sensitivity,.specificity,.accuracy of bile duct resident stones analyzed with DR imagines were 72%,.33.3%, 64.52%, respectively, while for DTS imagines were 88%, 66.7%, 86.67%. The score of DR imagines was 3.03±0.87,while that of DTS imagines was 4.03±0.79,.and there was statistical difference between two groups (P<0.01). Conclusion〓The clinical efficacy of DTS was better than that of DR, as showed higher sensitivity, specificity, accuracy of bile duct resident stones.

摘要: 【摘要】 目的 初步探讨数字断层融合技术(DTS)在胆道残石诊断中的临床应用价值。方法〓收集临床上诊断为肝胆管结石并行胆道手术后停留胆道引流管患者31例,均在常规数字化摄影(DR)直接胆道造影基础上加DTS断层成像,以胆道镜探查为参考标准,经影像医师对DR和DTS图像分别阅片诊断胆道残石、对图像评分分析两种方法图像显示效果。结果〓DR图像阅片方法诊断胆道残石敏感度72%、特异度33.3%、正确率64.52%;DTS图像阅片方法诊断胆道残石敏感度88%、特异度66.7%、正确率86.67%;DR图像得分3.03±0.87分、DTS图像得分4.03±0.79分,两者得分差异有统计学意义(P<0.01)。结论〓DTS成像技术对胆道残石诊断临床应用价值优于DR,且对胆道残石影像显示效果更佳。
