4D flow MRI imaging results in the porcine subjects. Top left—Porcine flow measurements pre-administration of noradrenaline and Top centre—porcine flow measurements post-administration of noradrenaline. The red shading indicates areas of higher flow measurements (cm/s). Porcine wall sheer stress measurements. Top right—porcine WSS measurements pre-administration of noradrenaline and Bottom left—porcine WSS measurements post-administration of noradrenaline. The areas of yellow-orange-red identify regions of higher WSS (Pa) in ascending order in the porcine subject. Bottom centre—Porcine pathline results pre-administration of noradrenaline and Bottom right—porcine pathline results post-administration of noradrenaline. The pathlines show the direction of blood flow during these stages
