Can generalized phase-contrast MRI quantify velocity and turbulence intensity downstream from different prosthetic heart valves in vitro?
Generalized phase-contrast MRI can quantify velocity and turbulence intensity downstream from prosthetic heart valves, revealing design-specific differences in turbulent kinetic energy.
