Whole-Heart, Free-Breathing 3D Cardiac Cine MRI with a cartesian, water-selective, balanced SSFP acquisition and spiral-like undersampling is combined with fast, non-rigid motion-compensated reconstruction. It demonstrates the feasibility of routine cardiac cine MRI with minimal planning effort and minimum patient discomfort by avoiding the need for breathholds. The combined acquisition and reconstruction time is below 5 minutes, including computation of deformation vector fields, and minimizes image production delay by starting reconstruction on partially acquired data.
