Figure 4

Comparison of helicity and vorticity metric measured at different proximal pulmonary arterial compartments. Helicity was significantly reduced in the pulmonary hypertension (PH) group in all considered regions (A), whereas vorticity was significantly reduced in the same group only in the right pulmonary artery (RPA) and when summarized over the entire considered vascular domain (B). CT indicates control; MPA, main pulmonary artery; NS, not significant; and RVOT, right ventricular outflow tract.
