The high frequency of radiographically evident cavities (in the study by Christensen and colleagues, nearly 98% of individuals had identifiable cavities) has probably declined with the trend toward earlier diagnosis. Decades ago the genus Mycobacterium consisted of approximately 30 species; today, more than 150 species are recognized. Chest radiography has a valuable role in monitoring patients with a confirmed diagnosis of MAC infection, whereas HRCT may detect earlier disease and suggest the diagnosis. ATYPICAL MYCOBACTERIA 1.
