There has recently been exploration into multi-contrast MPI, in which the signal from different tracer materials or environments is separately reconstructed, resulting in multi-channel images that enable temperature or viscosity quantification. In this work, we investigate the channel leakage in multi-contrast MPI reconstruction and we introduce a two-step measurement and reconstruction method to quantify and reduce channel leakage between multi-contrast MPI channels.en2365-903320241, suppl. 1Infinite Science Publishinghttps://creativecommons.org/licenses/by/4.0/Medicine, HealthJournal Article10.15480/882.952510.18416/IJMPI.2024.240302910.15480/882.9525Journal Article
