Objectives
Narrative objectives1 1.To assess and compare the pulmonary or myocardial blood flow and their heterogeneity of those flow in control subjects, patients with COPD, and in patients with PH.2.To compare the pulmonary blood flow assessed by 15O-H2O PET/CT and the diffusion capacity of carbon monoxide or transfer coefficient of the lung.in control subjects, patients with COPD, or with PH.Also in patient with PH, to compare the pulmonary blood flow assessed by 15O-H2O PET/CT and parameters of right heart catheterization, cardiac MRI,and Tc-MAA perfusion scintigraphy.3.To examine the pulmonary and myocardial flow reserve of blood flow in control subjects, patients with COPD, and patients with PH.4. To compare the pulmonary blood flow assessed by 15O-H2O PET/CT and the results of pulmonary function tests and scores of COPD activity test in patients with COPD. Particularly, to examine the relationships between quantity of the pulmonary blood flow assessed by 15O-H2O PET/CT and the severity of emphysema assessed by CT.
