Figure 3. CLR1502 accumulates to a greater extent in invasive compared to non-invasive tumors.

Radiant efficiencies were measured of specific regions of interest including normal intestine (n = 16), Peyer's patches (n = 19), non-invasive tumors (n = 7) and invasive cancers (n = 31) using the IVIS Spectrum. A statistically significant increase in total, average and maximum radiant efficiency was seen in the invasive cancers compared to the non-invasive tumors and normal intestinal tissues. * p value <0.05, ** p value <0.01.
