4D flow analyses. Systolic phase 4D flow image (A) was scaled to visualize peak flow velocity (B), measurement plane was selected from perpendicular planes (C–E) and analyzed (F) at the level of the highest flow velocity. Coronal oblique cine (G) and 4D flow (H) images demonstrating the different anatomical planes presented in Fig. 3B; valvular plane (1), the sinus of Valsalva (2), sinotubular junction (3), and the ascending aorta (4–5)
