Sliding slice MRI is a technique which uses a magnetization prepared sliding 2D slice to cast respiratory motion artifacts as geometric distortions rather than diagnostically obscuring ghosting routinely associated with 3D phase-encoding. In this work, we present the combination of simultaneous-multi-slice with pseudo-random Cartesian based sliding slice sampling. This combination allows increased frame rates, FOV tailoring, and reduces sensitivity to off-resonance compared to past non-Cartesian radial and spiral based approaches. Preliminary results are shown in moving phantoms and in-vivo free breathing DCE, demonstrating very good image quality.
