This two-center study compares pulmonary artery flow and
wall shear stress (WSS) measurements derived from two
different 4D Flow MRI sequences in subjects with
pulmonary hypertension (PH) and healthy controls.
Significant differences in flow and WSS were observed
between PH and control groups. Interobserver variability
for these measurements were negligible.
