Figure 3: T₂-weighted magnetic resonance images at various Fe concentrations CZF-MNPs and CZF-MNPs@ DMSA (1.5 T, Fast spin echo sequence: T_R=2520 ms, T_E=102 ms, room temperature) The T₂-weighted MR image shows that CZF-MNPs and CZF-MNPs@ DMSA induce a negative contrast. In addition, for the same Fe content, the enhancement in contrast using CZF-MNPs is the same as the amount of CZF-MNPs @ DMSA.
