Direct evaluation of peripheral airways using ultra-high-resolution CT in chronic obstructive pulmonary disease

ConclusionsU-HRCT enables accurate and direct evaluation of peripheral airways 1 to 2 mm in diameter. The 6th generation airways are commonly <2 mm in diameter, and the sum-LA can be a useful CT biomarker that reflects airflow limitation in COPD.
