1. A method for processing flow sensitive data of a region of interest, the method comprising: receiving a dataset of 4D flow magnetic resonance imaging (MRI) images corresponding to a scan of the region of interest; isolating a velocity component image from the dataset of 4-D flow MRI images; converting the velocity component image into a velocity vector field; determining at least one fluid dynamic quantity of the region of interest, wherein said at least one fluid dynamic quantity comprises pressure drop, which is estimated by integrating the velocity vector field over streamlines using a form of Bernoulli's equation; modeling a location of an anatomical wall within the region of interest; generating a visual representation of the anatomical wall and the at least one fluid dynamic quantity; and displaying the visual representation.
