A novel framework for 3D MRI of the fetus with retrospective motion compensation is developed and its initial feasibility demonstrated. This approach enables imaging with high isotropic resolution and allows for retrospective evaluation of the complex fetal anatomy in arbitrary scan planes, setting the stage for new possibilities in the assessment of fetal diseases in utero.
