3D time resolved MR angiography (MRA) and MRI applications often require large spatial coverage of the human body with high spatial and temporal resolution. In this presentation, a Cartesian Interleaved Variable Density sampling scheme is proposed and combined with parallel imaging and constrained reconstruction to meet these requirements. Different applications using the this method, including dynamic contrast-enhanced peripheral MRA, pulmonary perfusion and liver perfusion, will be discussed.
