Tailored and universal parallel transmit broadband pulses for homogeneous 3D excitation of the human heart at 7T

CONCLUSION: Broadband TP and UP can be used for homogeneous excitation of the heart volume across a 1300 Hz frequency range, including the water and the main six fat peaks, or with longer pulse durations and higher FAs for a smaller transmit bandwidth. Moreover, despite large inter-volunteer variations, broadband UP can be used for calibration-free 3D heart FA homogenization in time-critical situations.PMID:38440957 | DOI:10.1002/mrm.30072
