Representative magnetic resonance images of ischemic rat brains administered with bare FMNPs (a–d) and with SR-FLIVO-FMNPs (e–h). T2-weighted images (a, e), T2*-mappings of pre-injection (b, f), T2*-mappings of post-injection (c, g), and overlaid images of subtraction between before and after injection on T2-weighted images (d, h). There was no signal change between pre- and post-injection of bare MNPs (b, c). T2* signal reduction was prominently observed after injection of SR-FLIVO-FMNPs (f, g)
