Synopsis

Keywords: Flow, Cardiovascular

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.
