为评估CT支气管成像(CT brochography,CTB或称仿真支气管镜)对发现和诊断中央气道良性病变的补充价值,作者回顾性研究了1995～1998年28例病人(男18例,女10例,年龄6～71岁,平均40岁),其中中央气道良性病变24例,典型类癌4例。所有病人均行胸螺旋CT、CTB重建及纤维支气管镜检查。另有5例咯血病人,经螺旋CT和支气管镜检查,中央气道显示正常,作为对照组。因此该研究共检查了中央气道33例。纤维支气管镜检查由一 To assess the value of CT brochography (CTB) for the detection and diagnosis of central airway benign lesions, the authors retrospectively reviewed 28 patients (18 males, 10 females, Age 6 to 71 years, mean 40 years), of which 24 cases of central airway benign disease, typical carcinoid in 4 cases. All patients underwent spiral CT, CTB reconstruction and bronchoscopy. Another 5 cases of hemoptysis, spiral CT and bronchoscopy, the central airway showed normal, as a control group. Therefore, the study examined 33 cases of central airway. Fiberoptic bronchoscopy by one
