Virtual colonoscopy is an exciting new imaging technique with potential to alter current diagnostic approaches to colonic diseases, particularly colonic neoplasms. Although colonoscopy continues to offer the highest sensitivity and specificity for evaluation of the colon, virtual colonoscopy may offer greater safety, less discomfort, and consequently greater patient acceptance. In addition, virtual colonoscopy offers shorter procedure time, more accurate lesion location, and potentially lower cost as a screening test. Limited data are currently available to define virtual colonoscopy's full clinical role. This article describes the technical considerations, current clinical status, limitations, and potential indications of this new and exciting technology which gastroenterologists should not fear but embrace.
虚拟结肠镜检查是一项令人兴奋的新成像技术，有潜力改变目前对结肠疾病，尤其是结肠肿瘤的诊断方法。尽管结肠镜检查在评估结肠方面仍具有最高的敏感性和特异性，但虚拟结肠镜检查可能具有更高的安全性、更少的不适感，从而更容易被患者接受。此外，作为一种筛查测试，虚拟结肠镜检查的操作时间更短、病变定位更准确，且成本可能更低。目前关于虚拟结肠镜检查全面临床作用的数据有限。本文介绍了这项令人兴奋的新技术的技术要点、当前临床状况、局限性及潜在适应证，胃肠病学家不应惧怕而应欣然接受。
