Comparison of CT-Determined Pulmonary Artery Diameter Aortic Diameter and Their Ratio in Healthy and Diverse Clinical Conditions

摘要

BackgroundThe main pulmonary artery diameter (mPA), aortic diameter (Ao), and the mPA/Ao ratio, easily measured using chest computed tomography (CT), provide information that enables the diagnosis and evaluation of cardiopulmonary diseases. Here, we used CT to determine the sex- and age-specific distribution of normal reference values for mPA, Ao, and mPA/Ao ratio in an adult Korean population.
