Conditions

COPD(Chronic Obstructive Pulmonary Disease)

Interventions

Oxygen-enhanced MR images were obtained with inhaled oxygen as the T1 contrast agent. The T1-weighted images were continually collected by means of a respiratory synchronized.

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Clinically stable COPD patients with age 40 or over

Exclusion criteria

Exclusion criteria: Patients with any other major pulmonary diseases such as bronchial asthma, interstitial pneumonia, lung cancer and respiratory tract infection according to chest CT and other laboratory findings. Patients who are contraindicated for MRI. Patients judged to be inappropriate by physicians.

Design outcomes
