摘　　要：目的探讨多层面螺旋 CT(multi slice helical CT,MSCT)仿真胆道内窥镜的临床应用价值。方法 34例患者先行 B 超及 MSCT 普通扫描,然后行 MSCT 仿真内窥镜检查。对仿真内窥镜图像质量进行评价,由放射科及外科医生以双盲法分别做出诊断,并与最终诊断、B 超及 MSCT 普通扫描结果进行对比。结果仿真胆道内窥镜图像优质率为53.1%,可诊断图像率为96.9%。正确诊断率为93.8%,B 超正确诊率为61.8%,CT 正确诊率为46.7%。结论 MSCT 仿真内窥镜图像优质率及可诊断率高,可由外科医生独立阅片及诊断。MSCT 仿真胆道内窥镜正确诊断率高于 B 超及 CT。Objective To explore the clinical value of multi slice CT (MSCT) virtual endoscopy in bile duct examination.Methods MSCT virtual endoscopy was performed in 34 patients with suspected biliary diseases after routine ultrasonography and ordinary CT.Images of MSCT virtual endoscopy were reconstructed on the MSCT work station.The image quality was evaluated by two surgeons and the diagnoses made by radiologists and surgeons separately with double blind method.Results The fine quality rate of MSCT virtual endoscopy was 53.1%,the ratio of images which was possible for diagnosis to all images was 96.9%.The correct diagnosing rate of MSCT virtual endoscopy was 93.8% while those of uhrasonography and ordinary CT were 61.8% and 46.7%,respec- tively.Conclusions MSCT virtual endoscopy image has a high rate of fine quality.The surgeons can read MSCT image and diagnose diseases independently.The correct diagnosing rate of MSCT virtual endoscopy is higher than ultrasonography and ordinary CT.
