In vivo fluorescence imaging of Balb/c mice after intravenous administration of PEG-PCL micelles labelled with VivoTag 680XL. a 2D fluorescence imaging of Balb/c mice at 1, 4, 24 and 48 h after iv administration, ventral side. Fluorescence images are overlaid with light photography. Control is a mouse which has not been administered with VivoTag 680XL PEG-PCL micelles. b 3D fluorescence imaging-CT imaging co-registration of Balb/c mice at 1, 4, 24 and 48 h after iv administration, dorsal side and left side as shown. Heat map represents the area with fluorescence signal and color represents the intensity
