    Optical coherence tomography in imaging of peripheral pulmonary arteries

    Background: To establish an optical coherence tomography (OCT)-based method for imaging peripheral pulmonary arteries. Methods: We recruited eight patients (five men; average age, 48±12 years; peripheral pulmonary artery thrombosis, three patients; idiopathic pulmonary hypertension, three patients; interstitial lung disease, two patients) who underwent OCT of the peripheral pulmonary arteries in the First Affiliated Hospital of Guangzhou Medical University and Guangzhou Institute of Respiratory Diseases, between September 2009 and September 2010.
