Dual-isotope SPECT/CT images of tumor-bearing mice. (a) The mice were imaged 1 h after coinjection of 1.32 nmol ¹⁷⁷Lu—DOTA—cRGDfK (yellow-green colormap) and 1.32 nmol ¹¹¹In—DOTA—cRADfK (blue-purple colormap); (b) the mice were imaged 1 h after coinjection of 1.32 nmol ¹¹¹In—DOTA—cRGDfK (blue-purple colormap) and 1.32 nmol ¹⁷⁷Lu—DOTA—cRADfK (yellow-green colormap). The white arrows indicate the locations of tumor [23].
