Abstract: Objective To investigate the value of the CT 3D in the diagnosis of tracheobronchial foreign bodies. Methods 30 patients suspected of having tracheobronchial foreign bodies were subjected to HRCT scanning and 3D reconstruction. Images by HRCT and those under the stiff bronchoscope were compared to analyze the value of reconstruction. Results All 30 patients gained clear images. Foreign bodies were found at the same position shown by CT and operations in 23 patients, while they were moved in one, and they were negative in 3 patients examined by CT. One showed false negative images. Stiff bronchoscopy proved that one had a left bronchiostenosis and the other had inhalant bronchitis. Conclusions MSCT and imaging retro-processing techniques are valuable in judging tracheobronchial foreign bodies.
