Evaluation of non-selective refocusing pulses for 7Â T MRI

► We evaluate 21 non-selective refocusing pulses for performance at 7 T. ► BIR-4, SECH, version-S, and other B1-insensitive composite pulses are included. ► Pulses are tuned to target imaging applications in the human brain. ► Comparative analysis aids in choosing refocusing pulses for high-field applications.
