Validation of pre‐operative ${\mathit{R}}_2^{*}$ with 9.4 T ex vivo imaging of a resected hippocampus. Left: coronal slice of the pre‐op ${\mathit{R}}_2^{*}$ at 7 T with a zoomed‐in view of the sclerotic hippocampus before epilepsy surgery excision. Middle: magnitude image of the patient's resected hippocampus imaged at 9.4 T resulting in a 0.1 mm isotropic resolution (top); ${\mathit{R}}_2^{*}$ image of the hippocampus, where the subfield delineation was performed (bottom). Right: graph of comparison between pre‐op (blue) and ex vivo (purple) ${\mathit{R}}_2^{*}$ values within the subfields.
