Qmap is a multi-parameter mapping sequence that can acquire images for simultaneous T1, T2, and PD mapping within clinically acceptable acquisition times. Currently this is achieved with standard parallel imaging techniques applied to the individual slices. Potential exists to accelerate the acquisition further, especially if correlated information among the images is utilized. Compressed sensing and kat-ARC acceleration techniques were applied to a fully sampled Qmap acquisition. Synthetic images were produced with little error relative to the fully sampled acquisition, suggesting that synthesis of relative contrast images may be robust to the acceleration methods applied to the acquisition.
