In vivo and in vitro imaging of 131I-fulvestrant-ALA-PFP-FA-NPs: A In vivo fluorescence imaging of tumors in mice bearing tumors at different time points following intravenous injection of 131I-fulvestrant-ALA-PFP-NPs. B Changes in fluorescence signal intensity at corresponding time points within the tumor region. C Fluorescence imaging of excised major organs 24 h after intravenous injection of.131I-fulvestrant-ALA-PFP-NPs in mice bearing tumors. D Semi-quantitative analysis of average fluorescence intensity in various organs and tumors (Values are Mean ± S.D., n = 5)
