SPECT/CT imaging with [111In]1. a, b Representative SPECT/CT image of a mouse injected with [111In]1 at 6 h.p.i. (a) and 24 h.p.i. (b). The dotted lines indicate field of view of SPECT images. c Concentration of activity in tumor ROIs from SPECT images in kBq/ml, n = 6. d Activity in tumor, normalized injected dose tumor uptake %ID (n = 6). e TBR (tumor to heart) from SPECT signal, n = 6. f Adjacent cryosections from a dissected tumor. From top to bottom: autoradiography, NIRF imaging, and TUNEL staining. * for p < 0.05; ** for p < 0.01.
