Value CMR: Towards a Comprehensive, Rapid, Cost-Effective Cardiovascular Magnetic Resonance Imaging

Figure 5

2D phase-contrast and 4D-flow valvular imaging. Representative 2D phase contrast (PC) images and flow curves (a, b) and the corresponding 4D-flow maps and curves (c, d) at measurement sites across the mitral valve (a, c) and the tricuspid valve (b, d). The images show good agreement between flow curves by the two techniques, in addition to the extra information (pathlines and velocity maps) provided by 4D-flow acquisition. E: early filling peak; A: atrial filling peak.
