 Cardiac magnetic resonance tomography CMR provides a reliable technique to estimate elevated mean pulmonary arterial pressure from period of existence of a vortical motion of blood flow in the main pulmonary artery. Vortex can be visualized in 3-dimensional vector field, particle trace and streamline representations and can be analysed with respect to vortex related measures geometry of center, vortex formation, vorticity, propagation dynamics .... Furthermore T1-mapping and non-contrast enhanced lung perfusionventilation scans represent promising techniques for PH characterization.
