There has been previously proved that a metamaterial-based wireless coil (WLC) provided a 48-fold lower SAR in 1.5T wrist MRI in comparison to conventional RF setup. This can allow to extend the acceptable threshold of energy deposition for SAR-demanding pulse sequences. This study demonstrates that SLR-based FSE together with the WLC allowed to increase the slice selectivity while still being within the safe SAR limits. The actual energy deposition was decreased as compared to a conventional RF setup. The combination of this coil and SLR-based FSE offers an interesting alternative for investigations which require scanning in a “Low SAR” regim.
