Key result
Time-resolved three-dimensional relative pressure fields within the human heart can be noninvasively assessed by combining phase-contrast MRI velocity measurements with the pressure Poisson equation.
Noninvasive simultaneous assessment of cardiac pressure and flow phenomena using 3D phase-contrast MRI and computational fluid mechanics provides a new tool for studying cardiac fluid dynamics.

Offers noninvasive cardiac pressure mapping; leaves open prospective validation before clinical adoption.
Ebbers et al. (2002) studied Normal cardiac function (n=1). Time-resolved three-dimensional phase-contrast MRI and pressure Poisson equation was evaluated on Calculation of time-resolved three-dimensional relative pressure. Time-resolved three-dimensional relative pressure fields within the human heart can be noninvasively assessed by combining phase-contrast MRI velocity measurements with the pressure Poisson equation.
