Phase-contrast MRI (PC-MRI) is a well-established technique for quantification of blood flow and velocity. Quite often, for through-plane Flow Encoding (FE) 2D dynamic PC-MRI, the imaging slice may not be perpendicular to the blood vessel of interest and result in underestimation of peak velocity. Three-directional FE acquisitions may mitigate the underestimation but necessitate a lower temporal-resolution. We assume that the blood flow velocity direction does not change significantly between adjacent cardiac phases. We propose a fast 2D dynamic PC-MRI technique by using a constrain term of velocity direction to calculate flow compensation data using three-directional FE acquisitions Only (FEsO).
