Accelerated free breathing MRI with continously moving table using compressed sensing

Introduction In MRI with continuously moving table (CMT) breathing motion is an important issue. Recently motion compensation techniques for CMT-MRI during free breathing have been introduced [1, 2]. They apply parallel imaging to reconstruct multiple snapshots of the breathing motion from a fully sampled k-space and combine these snapshots subsequently. In this study the compressed sensing (CS) technique [3] is evaluated for the reconstruction of snapshots in free breathing CMTMRI. One snapshot per slice position without significant motion or reconstruction artifacts was reconstructed from a k-space randomly undersampled in phase encoding direction with a reduction factor of R = 2. Compared to other free breathing acquisitions, image details could be well resolved.
