Agreement between aortic flow-based and pulmonary flow-derived MRvol (MRvolAoi vs. MRvolMPAi) in four groups. a All HCM patients (black circles). b HCM patients with LVOT obstruction (red squares). c HCM patients without LVOT obstruction (blue circles). d Control subjects (green triangles). The Bland-Altman plots demonstrating agreement are shown. The solid line indicates the mean of the differences between two parameters (bias). The dashed lines indicate the upper and lower limits of agreement (mean ± 1.96 SD)
