MR imaging of C6 glioma xenograft tumor model. T2-weighted MR images of C6 glioma xenografts that were labeled with 25 μg/mL acetylated APTS-coated Fe3O4 NPs at (a) 7 days, (b) 14 days, (c) 21 days, and (d) 28 days. (e) The R2 mapping of C6 glioma xenografts that were labeled with 25 μg/mL acetylated APTS-coated Fe3O4 NPs at 14 days. (f) A pseudocolor picture of (e). (g) The R2 mapping of C6 glioma xenografts without labeling at 14 days as a control. (h) A pseudocolor photo of (g). The white arrows indicate the glioma xenografts.
