Doxorubicin fluorescence imaging. The upper section indicates an image of the 9-Gy-irradiated mouse. The lower section indicates an image of the not-irradiated mouse. The tumour site of the 9-Gy-irradiated mouse showed sufficient accumulation of doxorubicin in the upper section, whereas that of the not-irradiated mouse showed no significant accumulation of doxorubicin.
