Routine Pulmonary Function Test Can Estimate the Extent of Tuberculous Destroyed Lung
Figure 1
Some examples for grading the extent of TDL. (a) There was no abnormality, and a score of 0 was assigned. (b) A score of 1 was given, as less than 25% of the lung parenchyma showed destroyed lesion. (c) Destroyed lung lesion involved 50–75% of the lung parenchyma, and a score of 3 was assigned. (d) Destroyed lung lesion involved more than 75% of the lung parenchyma, therefore a score of 4 was assigned.
