  • Objective: To investigate the clinical value of chest fluoroscopy,chest radiography and high-resolution computed tomography(CT) in the diagnosis of atypical foreign body in trachea and bronchus.Methods: The data of chest fluoroscopy,chest radiography and high-resolution CT in 45 cases with atypical foreign body in trachea and bronchus diagnosed by fiberbronchoscopy were analyzed and compared.Results: The positive rate,false positive rate,false negative rate and misdiagnosis rate of chest fluoroscopy were 52.94%,17.65%,11.76% and 17.65%,respectively.The positive rate,false positive rate,false negative rate and misdiagnosis rate of chest radiography were 53.85%,15.38%,15.38% and 15.38%,respectively.The positive rate of CT was 100.00%,its false positive and negative rates were 0.00% and 0.00%,respectively.The difference of the positive rate in diagnosing the atypical foreign body in trachea and bronchus between chest fluoroscopy and chest radiography was not statistically significant(P>0.05),but the diagnosic positive rate of high-resolation CT and reconstruction were higer than the fluoroscopy and radiography(P<0.05).Conclusions: The sensibilities of chest fluoroscopy and radiography in diagnosing the atypical foreign body in trachea and bronchus are low,but CT detection is high.The CT detection is a reliable and noninvasive method for demonstrating the typical foreign body in trachea and bronchus.
