PEGylated Magnetite/Hydroxyapatite: A Green Nanocomposite for T2-Weighted MRI and Curcumin Carrying

Figure 7

The r2 relaxivity graph of PMHA nanocomposite shows a linear relationship between the inverse of the T2 relaxation times and Fe concentrations, inset: the T2-weighted MR image of the nanocomposite samples with various Fe concentrations. Reduction in the signal intensity with increasing the Fe concentration is seen.
