3D phase contrast blood flow measurements in the coronary arteries

Phase contrast MRI enables flow measurement in the coronary arteries. Herewith we propose a 3D Flow sequence and present a novel 3D visualization and quantification tool. Whole heart 3D PC measurements were performed in more than 20 healthy volunteers. An isotropic resolution of 1.2x1.2x1.2mm3 was used, as well as an undersampling factor of 14 in combination with a compressed sensing reconstruction. Our postprocessing tool was used for the 3D visualization of blood flow information as well as quantification of flow velocities per slice perpendicular to the vessel centerline.
