Results Multi-slice helical CT show all 14 foreign bodies, included 8 in trachea, 4 in left main bronchus, 2 in right main bronchus.
结果14例患者中，多层螺旋ct均直接显示气道异物。其中：气管异物8例，左主支气管异物4例，右主支气管2例。
The tumor seen here has caused obstruction of the main bronchus to left lung so that the distal lung is collapsed.
图示肿瘤导致左主支气管阻塞，因此远端肺组织塌陷。
Objective:To provide the applied anatomic basis for CT demonstration in left lower lobar bronchus.
