Difference of the progression of pulmonary cysts assessed by computed tomography among COPD, lymphangioleiomyomatosis, and Birt-Hogg-Dubé syndrome
Fig 5
The relationships between LAA_s and LAA% in all lung fields.
A and B: In COPD and LAM, LAA_s increased exponentially with LAA%. C: In BHDS, LAA_s did not correlate with LAA%.
BHDS: Birt-Hogg-Dubé syndrome; COPD: chronic obstructive pulmonary disease; LAA%: percentage of lung field occupied by low attenuation areas; LAA_s: mean size of LAA cluster; LAM: lymphangioleiomyomatosis.
