A method for real time 3D phase contrast imaging with highly undersampled FLASH and regularized nonlinear inversion reconstruction was developed. Flow in different directions was analyzed through invitro and invivo studies. 3D phase contrast maps were obtained in real-time for multiple cardiac cycles without ECG gating common in Cine 3D phase contrast MRI.
