Intravenous (i.v.) administration through the tail vein of 7.4 MBq of ¹⁸F-FDG for microPET imaging of LS174T xenograft mouse model. MicroPET imaging is shown at approximately 50 minutes after injection in coronal, maximum intensity projection, and transaxial views. Only very weak ¹⁸F-FDG activity was noted within the LS174T tumor implant. In contrast, significant tumor-nonspecific ¹⁸F-FDG accumulation was noted in the heart, Harderian glands within the bony orbits of the eyes, brown fat of the posterior neck region, kidney, and bladder.
