Deep learning CAIPIRINHA-accelerated 3D MRI of the knee cartilage at 7 Tesla

Three-dimensional (3D) dual-echo steady-state (DESS) sequences are widely used for magnetic resonance imaging (MRI) of the knee cartilage thanks to their high spatial resolution and capability of multi-planar reconstruction [1]. DESS sequences combine two gradient echoes separated by a refocusing pulse into a single image and increase the signal intensity of both articular cartilage and synovial fluid [2]. In addition, the reduced specific absorption rate of the sequence makes it particularly at…
