Figure Lengend Snippet: (A) Representative MR images from mice bearing 4T1‐GFP macrometastases at Days 28–35. (Ai,ii) Tumours imaged with RGD‐MPIO; (Ai) Nonenhancing tumour at Day 28, (Aii) Gadolinium‐enhancing tumour at Day 35. (Aiii–iv) Tumours imaged with RDG‐MPIO; (Aiii) Nonenhancing tumour at Day 28, (Aiv) Gadolinium‐enhancing tumour at Day 35. Each column of images, from the left, shows T 1 ‐weighted postgadolinium images, T 2 *‐weighted pre‐MPIO MGE3D images, T 2 *‐weighted post‐MPIO MGE3D images, and overlays on T 2 *‐weighted MGE3D images showing hypointensities pre‐MPIO and post‐MPIO. For the overlays, the tumour‐bearing striatum is segmented in green, and the contralateral striatum segmented in pink. Hypointense voxels are shown in red. (B) Significantly increased RGD‐MPIO–induced hypointense voxels were evident in the tumour‐bearing striatum (white bars) compared with the contralateral striatum (black bars) at Day 35 (two‐way paired ANOVA, p < 0.05). (C) Significantly increased control RDG‐MPIO–induced hypointense voxels were also seen in the tumour‐bearing striatum (white bars) compared with the contralateral striatum (black bars) at Day 35 (two‐way paired ANOVA, p < 0.05). (D–E) Comparison of pooled data across all timepoints for (D) Nonenhancing tumours, and (E) Gadolinium‐enhancing tumours. (D) Mice with nonenhancing tumours administered RGD‐MPIO (white bars; n = 7) showed significantly increased MPIO‐induced hypointense voxels in the tumour‐bearing hemisphere (one‐way ANOVA, p < 0.005) than both the contralateral hemisphere and the mice administered control RDG‐MPIO (black bars; n = 13) in the tumour‐bearing hemisphere. (E) In mice with gadolinium‐enhancing tumours, significantly increased MPIO‐induced hypointense voxels were observed in the tumour‐bearing striatum compared with the contralateral striatum for both RGD‐MPIO (white bars; n = 10) and RDG‐MPIO (black bars; n = 3) (one‐way ANOVA, p < 0.0001). However, in mice receiving control RDG‐MPIO, the volume of MPIO‐induced hypointense voxels was also significantly greater than those administered RGD‐MPIO.

Figure Lengend Snippet: Aggregations of iron in 4T1‐GFP tumour tissue. (A) Representative section of gadolinium‐enhancing tumour stained for Perls' Prussian blue (iron, blue) and counterstained with nuclear fast red. Black arrowheads indicate examples of single MPIO associated with the vascular endothelium, and red arrowheads indicate examples of iron aggregations. (B–C) Correlations between iron aggregations and tumour size in mice injected with either (B) RGD‐MPIO or (C) Control RDG‐MPIO. Linear regression analysis showed a positive correlation between number of aggregations and tumour size ( R 2 = 0.64, *** p < 0.001) in mice injected with RGD‐MPIO, but not control RDG‐MPIO, although a similar trend was evident; 95% confidence intervals are shown. (D–F) Consecutive sections stained for (D) Iba‐1 (macrophages and microglia, brown staining), (E) Prussian blue (iron), and (F) CD31 (blood vessels, brown staining) in a Day 35 mouse injected with RGD‐MPIO. The red arrow indicates a larger iron aggregation in a similar location to macrophage staining (D; Iba‐1), while the black arrow indicates single MPIO distant from macrophage staining, but close alignment with a blood vessel (F; CD31). (G–H) Double staining of 4T1‐GFP tumour tissue sections, from a mouse injected with RGD‐MPIO at the Day 35 timepoint, for Prussian blue (iron) and macrophages/microglia (Iba‐1, brown staining), indicate colocalisation of iron within macrophages/microglia (red arrows). Sections counterstained with nuclear fast red. (I) Double staining for Prussian Blue and CD31 revealed single MPIO (black arrow) bound to blood vessels (brown stained) in mice injected with RGD‐MPIO; representative image from Day 21 shown. (J) In the gadolinium‐enhancing 4T1‐GFP tumours, single endothelium‐bound MPIO are observed more often in mice injected with RGD‐MPIO ( n = 10) than control RDG‐MPIO ( n = 3, t ‐test, ** p < 0.01).
