Figure 2.

Serial measurements of intratumoral susceptibility signal intensity (ITSS) (white arrows) in the treated and control tumors on USPIO-enhanced SWI. In the treated tumors, ITSS is scored as grade 1 at 7 days (a), grade 2 at 14 days (b), and grade 2 at 21 days (c). In the control tumors, ITSS is scored as grade 3 at 7 days (d), grade 3 at 14 days (e), and grade 4 at 21 days (f). Smaller size is noted in the treated tumors than the control at each time point.
