The 3D concentric cylinders trajectory is an efficient and robust trajectory with fewer excitations than a comparable 3DFT trajectory and benign off-resonance effects. In this work, we applied an efficient parallel imaging strategy to 3D concentric cylinders, which decomposes the 3D non-Cartesian parallel imaging reconstruction into a series of 2D Cartesian reconstructions. Combined with the centric-ordered sampling scheme, this trajectory can be used to efficiently capture transient responses in a magnetization-prepared sequence.
