Extract

Introduction: A robust non-invasive method to estimate increased mean pulmonary artery pressure (mPAP) is needed. Recently, a 2D velocity encoding MRI study has shown that vortex duration in the pulmonary artery (PA) was related to mPAP (Reiter, Radiology,2015;275(1):71). This present study investigated the potential of 4D flow MRI to assess mPAP.

Methods: Thirteen patients with suspected Chronic Thromboembolic Pulmonary Hypertension (CTEPH) were assessed by right heart catheterization (RHC) and cardiac MRI, including a 4D phase contrast sequence. Streamlines were reconstructed in the pulmonary artery and the duration of the vortical blood flow, defined as closed concentric ring-shaped curves parallel to the pulmonary artery (PA), was measured as a % of the cardiac cycle. The vortex duration was compared to the RHC mPAP, right ventricular volume (RVV), PA diameter and PA distensibility.
