摘　　要：目的 :评价多层面螺旋CT仿真支气管镜 (CTVB)在中心型肺癌外科治疗中的应用价值。方法 :对 32例中心型肺癌的患者进行了多层面螺旋CT检查 ,将数据重建成CTVB图象。对与肺叶切除或全肺切除有关的支气管图像进行分析 ,并与纤维支气管镜的观察结果、手术及病理结果进行对照。结果 :CTVB可清晰显示全部的段以上支气管及 80 %以上的亚段支气管。对管腔狭窄、闭塞的显示与纤维支气管镜所见一致 ,但对肿瘤粘膜下浸润、粘膜充血、肿胀及出血 ,CTVB不能明确显示或区分 ,也不能进行活检。结合多层面螺旋CT的其他图像重建功能 ,能较完整综合地反映中心型肺癌支气管受侵的情况。结论 :CTVB是一种新的无创性观察支气管的方法 ,有独特优势 ,能为外科手术提供重要参考。Objective: To evaluate the clinical application of CT virtual bronchoscopy (CTVB) in predicting bronchial involvement from central lung cancer. Methods: Multislice spiral CT was done in 32 patients with central lung cancer. CTVB Images of bronchi that might affect lobectomy or pneumonectomy were reconstructed by means of imaging processing techniques. Then the related bronchi were assessed in comparison with fiberoptic bronchoscopy and pathologic findings. Results:CTVB could reveal 100% segmental bronchus, and 80% subsegmental bronchus. Narrowing or occluding of the lumen appeared as the view of fiberoptic bronchoscopy. But it could not observe mucosal abnormalities and perform biopsy. Conclusion:CTVB is a noninvasive method of observing airway with unique advantages. Combining with other image reconstruction methods of multislice spiral CT, it can be used to predict bronchial involvement from central lung cancer and to plan surgery.
