Title: The application value of high resolution CT in diagnosis and follow-up of pulmonary nontuberculous mycobacterial infection
Abstract: Objective:To explore the high resolution CT(HRCT) appearances of pulmonary nontuberculous mycobacterial infection and the value of HRCT in the diagnosis and follow-up of the disease.Methods:The HRCT findings of 50 cases with pulmonary nontuberculous mycobacterial(NTM) infection were reviewed.Among them,HRCT data before and after treatment were compared and analyzed in 23 patients.Results:The abnormalities involved more than 3 lobes in 47 patients,and the upper lobe was involved in 49 patients.HRCT findings:tree-in-bud sign and nodule were detected in all cases,patchy shadow in 47 cases,cavitiy in 29 cases,fibrosis in 29 cases,and bronchiectasis in 43 cases.Multiple manifestations often coexisted.HRCT performances of 23 follow-up cases:changes of imaging were not obvious in 10 cases,improved in 5 cases,slowly progressed in 8 cases,cavitiy developed from original pachy,ground-glass and nodule shadows in 6 cases.Conclusion:The chest HRCT has important value for the diagnosis and follow-up of lung NTM infection.
