Abstract: Medical imaging has become an important and indispensable diagnostic method in pulmonary tuberculosis and lung disease. Lesions morphological analysis is one of the important methods for the imaging diagnosis and differential diagnosis of pulmonary tuberculosis, enhanced CT scanning is the important supplement methods for the diagnosis of lesions morphology, magnetic resonance imaging (MRI) is the important diagnostic technology both morphology and molecular imaging, positron emission computed tomography computed tomography(PET-CT) imaging is also the important molecular imaging technology, and the value of these methods is to diagnose differentially and evaluate active tuberculosis lesions. Skillful mastering the purpose and meaning of different imaging techniques used in the diagnosis of pulmonary tuberculosis, pay great attention to imaging diagnosis and differential diagnosis in atypical pulmonary tuberculosis and smear negative pulmonary tuberculosis, and promoting multidisciplinary combine diagnosis including imaging morphological analysis, bacteriology, pathology,immunology, will be the main effort direction now and in the future.

Key words: Tuberculosis, pulmonary/radiography, Tomography, X-rey computed, Magnetic resonance imaging
