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.
