Dynamic contrast-enhanced magnetic resonance imaging provides parameters indicating permeability of tumor microvessels which has been shown to be closely related to angiogenesis. In this study, we tested that DCE-MRI can provide a non-invasive imaging biomarker to evaluate anti-angiogenic efficacy of macular degeneration. Our results demonstrated that there were significant changes between permeability parameters computed from drug treated and control group at 14 days (P < 0.01). These findings show the feasibility of permeability parameter as noninvasive biomarker for antiangiogenic drug evaluation in a mouse with choroidal neovascularization
