Abstract Objective: To evaluate relationship between CT imaging features and positive bronchoalveolar galactomannan(GM) for invasive pulmonary aspergillosis(IPA). Methods: One hundred and twenty patients with IPA were enrolled in this study． The levels of GM were measured in bronchoalveolar lavage(BAL)． Univariate logistic regression analysis was performed with GM in BAL and involved lung lobe number, existence of air crescent sign and halo sign． Result: The positive rate of GM in BAL is correlated with the number of involved lung lobes and existence of halo sign on CT. Conclusion: GM in BAL may be an important marker for diagnosing IPA, and GM in BAL is correlated with CT features.
