Ultrafast gradient insert coils can boost EPI performance when designed as an independent 4th gradient chain. However, at high operating frequencies, substantial eddy currents will be generated in the shields of RF coils. Here we show that RF shields can be removed without compromising MRI performance yet enabling two orders of magnitude increased gradient efficiency at high frequency.
