Pulmonary infection in hematological malignancies (HM) is one of the common and frequent diseases in clinical practice. Early

accurate and rapid determination of pathogen types is the key to treatment. The traditional detection methods have certain reliability but present many shortcomings. In recent years

with the continuous development of metagenomic next generation (mNGS) technology in clinical practice

the application of mNGS of pathogens in the diagnosis of pulmonary infection lesions reflects a certain value

and HM often has certain clinical and computed tomography (CT) imaging characteristics in different stages of various pulmonary infections. This article focused on mNGS and CT examination methods

and reviewed and analyzed their respective characteristics and the current status of the diagnosis of HM pulmonary infection.
