Comparative analysis of SINC-shaped and SLR pulses performance for contiguous multi-slice fast spin-echo imaging using metamaterial-based MRI

Discussion and conclusionSLR-based FSE together with the metadevice allowed to increase the slice selectivity while still being within the safe SAR limits. The “slice cross-talk” effects were conditioned by the number of echoes in the echo train, the repetition time, and T1 relaxation times. The approach was more beneficial for T1-weighted SLR-based FSE as compared to PD-weighted. The combination of the metadevice and SLR-based FSE offers a promising a lternative for MR investigations that require scanning in a “Low-SAR” regime such as those for children, pregnant women, and patients with implanted devices.
