CT imaging of the uptake and distribution of IX-lipo in CT26 tumors. (A) 2D axial CT images of a representative mouse at different time points; (B) 3D CT images of a mouse at 72 hours post-injection; (C) Relative changes in mean CT values of the entire tumor post-injection; (D) Fluorescence microscopy images confirming the distribution of IX-lipo in the tumor, with rhodamine-labeled IX-lipo shown in red and cell nuclei in blue (DAPI). In panels A and B, tumors are indicated by yellow arrows.
