目的　探讨仿真内镜成像的临床胃肠道应用价值。方法　对病理证实的８ 例大肠病变和１ 例胃癌患者（ 共１１ 个病灶） 进行了ＭＲＶＥ和内镜检查，其中１ 例同时进行了ＣＴＶＥ 检查。ＭＲＶＥ 应用ＨＴ２ＦＳＥ 序列无间隔扫描，层厚２ ～３ｍ ｍ 。ＣＴＶＥ应用５ｍ ｍ 准直层厚，２５ｍ ｍ 重建间隔，螺距为１０ ，屏气下一次扫描全结肠。用导航软件行内镜成像重建。结果　９ 例均获得了内镜样影像，ＭＲＶＥ 对病灶的检出率为８１８ ％ ，准确性为６９２ ％ ，２ 个直径０６ｍ ｍ 以下病灶未检出；结合导航多方位影像和／ 或源影像可靠显示了病变部位并区分了病变与伪影，使其准确性提高到１００ ％ 。ＣＴＶＥ准确显示了该例结肠癌病变，１ 个０６ｍ ｍ 直径息肉漏检。仿真内镜成像显示胃肠粘膜和病灶表面细节无电子内镜好（ Ｐ＜ ００５） 。结论　仿真内镜成像无创性获得了胃肠道内镜样解剖图像，并准确地检出了直径１２ｍ ｍ 以上肿块病变 Objective To explore the value of clinical endoscopy in the simulation of endoscopic imaging. Methods Eight cases of colorectal lesions and one case of gastric cancer (11 lesions) confirmed by pathology were examined by MRVE and endoscopy. CTVE examination was performed in 1 case. MRVE application HT2 FSE sequence non-interval scanning, layer thickness 2 ~ 3m m. CTVE application of 5m m collimation layer thickness, 2  5m m reconstruction interval, pitch 1  0, hold the next scan the whole colon. Endoscopic reconstruction with navigation software. Results All the 9 cases were endoscopic - like. The detection rate of MRVE was 818% and the accuracy was 692%. Two lesions of 06m in diameter were not detected. Combined with navigation multi - orientation images And / or the source image reliably displays the lesion and distinguishes between lesions and artifacts, increasing its accuracy to 100%. CTVE accurately shows the case of colon cancer lesions, a 0  6m diameter polyp missed. The simulated endoscopic imaging showed that the details of the gastrointestinal mucosa and lesion surface were good without electronic endoscopy (P <005). Conclusions The endoscopic imaging of the gastrointestinal tract was obtained by non-invasive simulation of endoscopic imaging and accurately detected the lesion of more than 12m in diameter
