Figure 5.
A: the relationship between tumor size and tumor uptake for 99mTcO(MAG2-3P-RGD2) at 120 min p.i. in the athymic nude mice (n = 14) bearing the U87MG glioma xenografts. The linear relationship between the tumor size and %ID tumor uptake suggests that 99mTcO(MAG2-3P-RGD2) has the potential for noninvasive monitoring of tumor growth or shrinkage during anti-angiogenic therapy. B: planar images of the athymic nude mice (bearing U87MG glioma xenografts) administered with ∼500 μCi of 99mTcO(MAG2-3P-RGD2) at 15, 30, 60 and 120 min p.i. Arrows indicate the presence of the tumor, gallbladder, kidneys and bladder.
