Published ahead-of-print in JTI is an exciting review article by MD Hope et al. entitled “Cardiothoracic Magnetic Resonance Flow Imaging.” This article highlights new techniques in phase contrast (PC) MRI that can evaluate hemodynamics of the cardiovascular system. This article summarizes the techniques for performing and analyzing 3-D cine PC-MRI (4-D flow) and describes different metrics than can be measured or calculated using this technique. Topics discussed in this article include flow volume, flow eccentricity, pulse wave velocity, pressure, turbulence, wall shear stress, and flow connectivity. Applications for aortic, pulmonary arterial, and cardiac disease (including complex congenital heart disease) are reviewed. The high quality written material is augmented by stunning figures highlighting the power of these new techniques for illustrating the hemodynamics of the cardiovascular system.
