Intravenous (i.v.) administration through the tail vein of 0.6 MBq of ¹²⁴I-HuCC49deltaC _H 2 for microPET imaging of the LS174T xenograft mouse model. MicoPET imaging is shown at approximately 1 hour and at 23 hours after injection in coronal, sagittal, and transaxial views. At 23 hours after i.v. injection, ¹²⁴I-HuCC49deltaC_H2 was found to have specifically accumulated within the LS174T tumor implant.
