Magnetic Resonance Imaging Provides Non-Invasive Assessment of Pulmonary Hypertension Severity by Reduced Relative Area Change of the Pulmonary Artery

Abstract

INTRODUCTION Pulmonary arterial hypertension (PAH) is a disease of the distal pulmonary arteries that results in an elevation in pulmonary arterial resistance and pressure [1]. Currently, right heart catheterization is the gold standard for assesment of PAH. The relative cross sectional area change (RAC) of the main pulmonary artery may be a useful non… (More)
