目的：探讨ＣＴ新技术仿真内窥镜的临床应用价值。方法：对４０例患者及正常人（鼻部１７例、喉７例、气管支气管５例、胃４例、结肠７例）行螺旋ＣＴ扫描后经软件处理进行仿真内窥镜成像，并与纤维内窥镜、手术所见对照研究。结果：ＣＴ仿真内窥镜显示正常解剖结构、病变位置，范围与纤维内窥镜所见类似，并可进入纤维内窥镜无法到达的腔道，如副鼻窦内、狭窄的管腔内以及梗阻病变的远端。结论：ＣＴ仿真内窥镜提供了一种无创性的诊断方法，可作为纤维内窥镜的补充手段，具有一定的应用潜力，值得临床上进一步推广应用。
Objective: To explore the clinical value of CT new technology simulation endoscope. Methods: 40 cases of patients and normal people (17 cases of nose, 7 cases of larynx, 5 cases of tracheobronchial, 4 cases of stomach and 7 cases of colon) underwent spiral CT scans and simulated by endoscopic imaging with fiber Endoscopy, surgery see control study. Results: The CT simulation endoscope showed normal anatomy, the location and extent of the lesions were similar to those seen with fiber endoscopy, and were accessible to unreachable intracavitary channels such as paranasal sinus, narrow lumen, and obstruction Distal lesions. Conclusion: CT simulation endoscopy provides a noninvasive diagnostic method, which can be used as a supplementary means of fiber endoscopy, has some potential applications, it is worth further clinical application.
