Multiplanar reformatted (MPR) plane analysis for direct jet tracking. 1 Velocity color-coded 4D flow data of the left atrium (LA), left ventricle (LV), and aorta (Ao) in mid-systole show an MR jet in the left atrium (LA). To illustrate proper MPR plane placement, three candidate planes A, B, and C (white lines) are placed in the MR jet with increasing distance from the mitral valve. 2 Color-coded and corresponding grayscale through-plane velocity images are shown for planes A–C. Only plane C is suitable for analysis because it contains the maximum velocity without aliasing. Planes A and B are unsuitable due to aliasing within the MR jet (red arrows). 3 For plane C, vector glyphs with double-oblique views are used to orient the plane perpendicular to the MR jet flow. 4 The through-plane velocity of the MR jet is carefully segmented to calculate regurgitant flow rate. This analysis is repeated for each timeframe with MR
