Abstract:Purpose
Four-dimensional (4D) magnetic resonance imaging (MRI) is used to determine abnormal blood flow in patients with pulmonary hypertension (PH), but the relationship between abnormal blood flow and pulmonary artery volume is unclear. This study aimed to quantify pulmonary artery volume and flow parameters using 4D flow MRI, and to evaluate their relationship in patients with PH and in those without PH.
Methods
We retrospectively studied 177 patients at our institution who underwent cardiac contrast-enhanc… Show more
