The representative cases according to chest CT classification.
(A) definitely-active, with lesions including a cavity (B) probably-active, showing a “tree-in-bud” appearance or multiple non-calcified poorly circumscribed nodules without a cavity (C) indeterminate-activity, with lesions appearing mainly as non-calcified well-circumscribed nodules (D) probably-inactive, with lesions appearing mainly as calcified nodules or fibrotic bands.

MTB culture yield according to radiographic activities of chest CT (A) and final diagnosis as definite or probable PTB by each radiographic grades (B).
MTB = Mycobacterium tuberculosis Definite TB, defined as microbiologically, histologically or genotypically confirmed cases Probable TB, defined as clinically diagnosed case.
