Recent Publication: In Vivo Evaluation of Population-Specific Inversion Pulses in Parallel Transmission

MBCIU team members Igor Tyshchenko, Simon Lévy, Joseph J. Bartlett, , Yasmin Blunck, Tudor V. Sava, Rebecca Glarin, and Leigh A. Johnston along with Bahman Tahayori, Kelvin Chow, and Patrick Liebig have recently published a paper titled "In vivo evaluation of population-specific inversion pulses in parallel transmission."

While a "one size fits all" universal pulse is commonly used in parallel transmission, it does not account for individual anatomical differences and may lead to suboptimal image quality. Calculating tailored pulses for an individual can improve performance, however it is often clinically infeasible as it is time-consuming. We have developed a pipeline that classifies head shapes into one of five clusters, in-line, utilising data from the localiser scan. It then selects a pre-computed inversion pulse for an MP2RAGE sequence that has been tailored for that cluster. This approach does not increase scan time and thus brings sub-population pulses closer to clinical application.
