the aim of the study was to characterize the mechanical properties of the pulmonary arterial wall (PA) in patients with pulmonary arterial hypertension (PAH) using magnetic resonance imaging (MRI) of the heart, and to determine their diagnostic and prognostic value. ⋯ The MRI pulsation index is the simpleststiffness index of the pulmonary artery wall and the most promising one for evaluating the prognosis of patients with PAH.
