Signal-intensity decay and map of T₂ values in the rat brain. (a) Signal-intensity decay of different regions of interest (ROIs) at different TEs, showing the different MR-relaxivity properties of different brain regions at 14 days after the lesion and after cell implantation. Map of T₂ values (ms) within the rat brain. (b) Because of the superparamagnetic properties of iron oxide particles, labeled cells induced a decrease of T₂ value at the site of implantation (arrow 1), and at the LPS lesion site (arrow 2).
