Flow sensitive 4D MRI permits the measurements of three directional blood flow velocities. The acquired data can be used for analysis of blood flow as well as to derive additional information on vessel geometry by time-averaged 3D phase contrast angiography. The derived vessel boundaries are useful for calculation of cardiovascular pressure gradients, which are an important clinical marker for the evaluation of the severity of disease.
