Keywords: Quantitative Imaging, Brain, T2 mappingWhile recent works have determined that the DESS sequence has the ability to produce 3D T2 mapping of the brain, it remains sensitive to B0-related variation due to respiration. Multiple encoding strategies, using cartesian-spiral trajectories with different lengths combined with a variable density Poisson undersampling mask and Compressed-Sensing reconstruction, were consequently employed and compared in order to suppress respiration artifacts as well as to establish accurate and repeatable 3D T2 maps of the brain at 3T.
