Myeloarchitecture has a critical role in the specialisation of brain microcircuitry. It shapes network functions from small to large scale, and ultimately behaviour. We tested, on homemade Agar gel phantoms, the multi-shot inversion recovery slice shuffled EPI IR-MS-EPI approach recently proposed by Sanchez and co-workers (Proc. Intl. Soc. Mag. Reson. Med. 2018, 60). Our measurement results and the simulated performances of MS-IR-EPI showed a good reproducibility of the T1 maps and a preserved quality of its point spread function, when acquiring at higher-than 500μm in-plane resolution, making it suitable for assessing grey matter myelination process.
