Pulmonary tuberculosis is an endemic infection. Chest radiography is the mainstay in the evaluation of pulmonary tuberculosis. High resolution CT is required to detect fine lesions overlooked on chest radiographs, to define equivocal lesions, to determine disease activity in some cases and to evaluate complications or sequels. We review indications of chest radiograph and CT, the radiologic features of primary and post-primary tuberculosis, and outcome of tuberculous lesions.
