SPECT/CT images of tumor bearing mice. A,B and C are coronal SPECT/CT images 5 h after administration of 111In-DTPA as well as 5 h and 24 h after administration of 111In-NPs. The gray outline of the animal is seen in the CT image while the colored areas are the co-registered SPECT image of the 111In distribution. A 3D volume rendering image is shown in D. These images show that the radioactivity associated with 111In-NPs accumulates in the tumor region (along with significant liver accumulation) while radioactivity associated with 111In-DTPA does not. E shows the whole body retention of radioactivity following administration of 111In-NPs and 111In-DTPA.
