摘要
目的评价螺旋CT仿真内窥镜在喉部病变诊断中的临床应用价值。方法为39例患者使用螺旋CT扫描后经软件处理行仿真内窥镜成像,并与纤维喉镜对照。结果喉部病变39例中CT仿真内窥镜从头端入路,显示喉内解剖结构,病变位置,形态,大小,范围情况与纤维喉镜所见基本一致,而从足端入路可显示纤维喉镜不能显示的病变声门下及气道狭窄远端情况,而对于小的,扁平病灶CT内窥镜显示欠佳。结论CT仿真内窥镜是一种无创性安全检查方法,可作为纤维喉镜的补充检查手段,具有一定发展潜力。
Objective To assess the usefulness of spiral CT virtual endoscopy（CTVE） in diagnosis of laryngeal lesions.Methods The virtual endoscopy images that were set up according to CT scan and software processing were compared with that of actual laryngoscopy in 39 patients. Results CT virtual endoscopy showed the normal anatomical structure of larynx and the location, extension, morphology,size of the lesions of larynx from head to feet.39 patients with laryngeal lesions showed in CT virtual endoscopy agreed with that of actual laryngoscopy. In addition,CT virtual laryngoscopy revealed the structure of subglottic region and distal portion of strictured airway from feet to head. But the lesions with small sized and flat were showed pooly, Conclusion CT virtual laryngoscopy is used as a non-invasive examination method, It is a good comple mental method of fiber optic laryngoscopy.
