Thin (2mm) section contiguous computed tomographic (CT) scans were obtained through the bronchi of the right upper lobe and the left upper division in 30 patients. All segmental bronchi were identified. The right subsegmental bronchi were identified in 100%, and the left subsegmental bronchi in 97%. The type of the orifice of the right bronchus was trifurcated (53%), the extension of B1 was apicoanterior (50%), and the size of B2b was equal to B3a (63%). The extension of the left B3 was subapicoanterior (38%), and the size of B1+2c was equal to B3a (62%).
对30例患者的右上叶支气管和左上叶支气管进行了2毫米薄层连续计算机断层扫描（CT）。所有段支气管均被识别。右亚段支气管的识别率为100%，左亚段支气管的识别率为97%。右支气管开口类型为三分叉（53%），B1的走行为尖前段（50%），B2b的大小等于B3a（63%）。左B3的走行为亚尖前段（38%），B1+2c的大小等于B3a（62%）。
