We present experimental data to verify theoretical findings on how to select the RF parameters of a non-selective SPGR pulse train to maximize signal amplitude and T2 contrast in tissues with fast transverse relaxation. The experimental data very closely matched the theory so that our results may directly be implemented to maximize the scan efficiency of UTE acquisitions.
