In this study, we showed the novel application of dynamic pTx pulses for diffusion MRI on a Siemens 7T Terra scanner, with an 8Tx32Rx Nova head coil. We compared the performance of subject-specific spokes pulses against traditional circularly polarised pulses in a healthy volunteer. We observed that pTx pulses improves the signal across the whole brain, especially in lower brain regions like the cerebellum. This leads to improved definition of diffusion tracts and higher FA values in the regions of interest. In conclusion, this work demonstrated the feasibility and benefits of using pTx pulses for diffusion MRI at 7T.
