Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To elucidate the accuracy and inter-rater agreement of diagnosis of nontuberculous mycobacterial lung disease based on chest CT, two pulmonologists and two chest radiologists were requested to interpret chest CT of patients nontuberculous mycobacterial lung disease satisfying diagnostic criteria of American Thoracic Society as well as British Thoracic Society, or pulmonary tuberculosis. Two pulmonologists and two chest radiologists \> 10 years of clinical experiences at a tertiary referral hospital participated as raters in this study. They were blinded to the any clinical information of the patients including the specific diagnosis, except age and sex. The interpretations of four raters were analyzed and compared.
