In this study, a high-resolution 3D MR Fingerprinting technique, combining parallel imaging and deep learning, was developed for rapid and simultaneous quantification of T₁ and T₂ relaxation times. Our preliminary results show that, with the integration of parallel imaging and deep learning techniques, whole-brain quantitative T₁ and T₂ mapping with 1-mm isotropic resolution can be achieved in ~6 min, which is feasible for routine clinical practice.
