Purpose To compare pulmonary artery flow using Cartesian and radially sampled four‐dimensional flow‐sensitive (4D flow) MRI at two institutions. Methods Nineteen healthy subjects and 17 pulmonary arterial hypertension (PAH) subjects underwent a Cartesian 4D flow acquisition (institution 1) or a thre...
