Value of coronal CT scan for airway disease in children / 重庆医科大学学报

ABSTRACT

Objective:To explore the value of direct coronal CT scan for airway disease in children. Methods:The clinical and imaging data of the lung and airway disease of eighty-seven cases were retrospectively analyzed.Chest film(48 with chest fluo- roscopy) the cross and coronal CT scan were performed and confirmed by tracheal endoscopy operation in all cases. Results: The main X-ray signs on chest film(fluoroscopy) and the cross CT were obstructive emphysema obstructive pneumonia or at- electasis. The coronal CT displayed 68(78.2%) cases with foreign body of which 64 cases were positive and 4 cases nega- tive;3(3.4%)cases with tracheal bronchus; 2 of which with the right upper lobe bronchus arising from the tracheal 1case with the apical and posterior segment of the right upper lobe bronchus arising from the tracheal;7(8.0%) cases with tracheal- bronchus Stenosis1 case with the cross diameter of the tracheal narrow 4 cases with the left bronchus narrow 2 cases with tracheal narrow compressed by esophagitis foreign body;2(2.3%) cases with trachea stenosis associated with tracheal bronchus 1 case with the cross diameter of the tracheal narrow and the tracheal diverticulum above the carina the other one with the right tracheal-bronchus,then tracheal stenosis above the carina;4(4.6%) cases with bronchitis;2(2.3%) cases with bronchus granuloma.1(1.2%)cases bronchus TB. Conclusion:Axial and Direct coronal CT scanning can demonstrate the cause of some lung and airway diseases,provide evidence for the differential diagnosis in children and be helpful in planning virtual flexible bronchoscopy.
