3D dynamic contrast enhanced (DCE) pulmonary perfusion imaging for simultaneous evaluation of vascular anatomy and a dynamic assessment of parenchymal microvascular enhancement has been a long sought after application and is finally becoming achievable due to recent advances in rapid imaging. However, it poses challenges for the required resolution in the spatial-temporal domain. In this work, we demonstrate the feasibility of using the DISCO (Differential Subsampling with Cartesian Ordering) technique for DCE pulmonary perfusion to achieve the necessary high spatial-temporal resolution for this application.
