摘　　要：结直肠疾病是一种常见疾病,CT仿真内窥镜(computed tomography virtual endoscopy,CTVE)在结直肠疾病诊断中的应用近年受到广泛重视.本文通过文献检索,结合作者的应用经验和体会,探讨CTVE的技术原理、肠道准备和检查方法,总结CTVE对结直肠疾病的诊断价值,结果发现CTVE可以全面观察结直肠肿瘤、息肉、炎症等病变的形态特征,不仅可以显示结直肠病变的部位、形态、大小,而且可以明确结直肠癌的肠壁受侵范围、周边组织关系及远处转移情况,但也存在着发现病变后不能活检或治疗的局限性.因此,CTVE被认为是一种快速、方便、安全、无创、有效的结直肠检查新方法,可作为结、直肠疾病的筛查手段和普查方法加以推广应用.Colorectal diseases are a group of common diseases.In recent years,extensive attention has been paid to the application of computed tomography virtual endoscopy（CTVE） in the diagnosis of colorectal diseases.Through the literature search,combined with the author＇s experience,we explore the technical principle,bowel preparation and inspection method of CTVE,making a summary of the value of CTVE in the diagnosis of colorectal diseases.CTVE can fully observe morphological characteristics of colorectal cancer,polyps,and inflammatory disease.CTVE can not only determine the lesion location,shape,and size,but also confirm the extent of invasion into the colorectal wall,surrounding tissue and distant metastasis.However,the main limitation is that the detected lesion cannot be biopsied or treated during CTVE.Therefore,CTVE is a new,rapid,convenient,safe,non-invasive,and effective method for colorectal examination,which can be used for screening of colorectal diseases.
