Abstract: Tuberculosis (TB) is still one of the major infectious diseases in the world, and the incidence of Drug-resistant pulmonary tuberculosis (DR-PTB) is the focus and difficulty of tuberculosis control. Early, rapid and accurate diagnosis of DR-PTB is essential for selecting appropriate and personalized treatment and is an important means of reducing disease transmission and mortality. In recent years, the imaging diagnosis of DR-PTB has developed rapidly, but there is a lack of consistent understanding. To this end, Infectious Disease Imaging Group, Infectious Disease Branch, Chinese Research Hospital Association; Infectious Diseases Group of Chinese Medical Association of Radiology Digital Health Committee of China Association for the Promotion of Science and Technology Industrialization.et.led the organization of tuberculosis clinical and imaging experts across the country, referring to the diagnosis and treatment status of DR-PTB at home and abroad, combined with China's clinical practice and evidence-based medicine on the methodological requirements of guidelines and standards. After repeated discussion, the expert consensus of imaging diagnosis of DR-PTB was formed. Its contents include clinical diagnosis and classification of DR-PTB, selection of etiology and imaging examination, imaging manifestations, diagnosis and differential diagnosis. This expert consensus is expected to improve the understanding of the imaging changes of DR-PTB, as a starting point for timely detection of suspected DR-PTB patients, and can effectively improve the efficiency of clinical diagnosis and achieve the purpose of early diagnosis and treatment of DR-PTB.
