T2 Relaxation Time Obtained from Magnetic Resonance Imaging of the Liver Is a Useful Parameter for Use in the Construction of a Murine Model of Iron Overload

Figure 1

(a) Representative proton-density-weighted images of livers (indicated by white arrow) on Day 3 after administration of iron-dextran or dextran (control = dextran; Iron 0.1 = 0.1 mg iron-dextran/mouse; Iron 0.5 = 0.5 mg iron-dextran/mouse; Iron 2.5 = 2.5 mg iron-dextran/mouse). (b) R1, (c) R2, and (d) of MRI of livers on Day 3 after administration of iron-dextran or dextran (control = dextran; Iron 0.1 = 0.1 mg iron-dextran/mouse; Iron 0.5 = 0.5 mg iron-dextran/mouse; Iron 2.5 = 2.5 mg iron-dextran/mouse). Results are expressed as mean + SD. Five mice from each group were used. Statistical significances were analyzed by Dunnett’s test. .
