多层螺旋CT仿真内镜在中央型肺癌中的应用价值

Value of Multi-slice Helical CT Virtual Endoscopy in Diagnosing Central Bronchogenic Carcinoma

目的:探讨多层螺旋CT(multislice computed tomography,MSCT)仿真内窥镜在中央型肺癌中的临床运用价值.方法:48例中央型肺癌行MSCT薄层扫描后进行VE成像,其中23例与纤维支气管镜(fi-brobronchoscope,FBS)检查对照.结果:仿真内镜(virtual endoscopy,VE)下表现为支气管管腔闭塞33例,支气管凸凹不平,偏心狭窄15例,23例VE与FBS对照符合率达93.3%.结论:MSCT VE可很好的辅助判断中央型肺癌的支气管狭窄部位和程度.

Objective： To discuss the clinical value of multi- slice helical CT virtual endoscopy （VE） in diagnosing central bronchogenic carcinoma. Methods： Multi - Slice helical CT VE was performed in 48 patients with central bronchogenic carcinoma, of which 23 cases with fibrobronchoscope （FBS） as contrast. Results： VE findings included bronchial obstruction （ n = 33）, eccentric stenosis of bronchus or trachea （ n = 15）. The consistency of findings between VE and FBS was up to 93.3%. Conclusion： Multi - slice helical CT virtual endoscopy is helpful for identifying the location and degree of bronchial stenosis in central bronchogenic carcinoma.
