A 2D multi-contrast sequence with deep learning-powered reconstruction is developed to generate four contrast images (PDw, T1w, T2w, and FLAIR) and two quantitative maps (T1 and T2) in 2 minutes of scan time. For the reconstruction, a new deep learning method that assures both data consistency and image fidelity is applied with the joint reconstruction of the quad-contrast k-space data.
