Spin echo functional MRI in bilateral auditory cortices at 7Â T: An application of B1 shimming

► B1 shimming is used to optimize RF efficiency in the bilateral auditory cortex. ► We acquire SE-EPI fMRI data at ultra high fields in the bilateral auditory cortex. ► With SE-fMRI we obtain single subject and group tonotopic and voice selective maps. ► Our results highlight the feasibility of using B1 shimming to acquire SE-EPI data.
