At frequencies above 150 MHz, shielded loop coils become impractical because capacitive tuning is no longer possible. The integration of a floating secondary shield allows adaptation of this design to higher magnetic fields. Simulations and initial experiments suggest that a double-shielded dual-loop coil may be used for continuous arterial spin labeling at the human neck at 7 T within legal SAR limits.
