Abstract
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.
