Abstract

The dynamic three dimensional velocity vector mapping method using phase-contrast-magnetic resonance imaging (PC-MRI), to visualize the complex flow pattern through 3-dimensional (3D) volume rendered images displayed dynamically, was discussed. A phantom study was performed to evaluate the accuracy of the PC-MRI in continuous and pulsatile flow measurement. The 3D velocity vector mapping was applied to the flow analysis around the artifical heart valve in a flat phantom. The analysis suggested the calculation of cardiac output from totally implantable artificial heart (TAH) sac by quantitative measurement of the volume of flow across the outlet valve.
