Pulmonary hypertension (PH) is a severe vascular disorder that may affect 50% of patients with heart failure.
This retrospective study’s aim was to evaluate whether 4D flow magnetic resonance imaging (MRI) can be used to quantitively measure flow parameters to identify patients with PH.
The show that these data suggest that 4D flow MRI can quantitate pulmonary artery flow parameters and distinguish
between patients with and without PH.
