Impaired lung deformation during expiration in chronic obstructive pulmonary disease using four-dimensional dynamic-ventilation CT
Decreased lung deformation during expiration was associated with loss of lung function. Strain-related parameters, especially those derived from the whole expiration phase, showed promising values in reflecting the severity of airflow limitation in patients with COPD.
