In December 2006, we received the first ever Inveon hybrid microPET/CT scanner from Siemens. Coupled with our own proprietary cell-selective imaging contrast agents, this scanner affords our investigators unique disease detection and evaluation which can only be provided at the UW. This scanner provides unsurpassed PET sensitivity (>10%), 1.2mm resolution, and a large axial field of view (13 cm). The anatomical CT and the functional PET images are automatically co-registered for easy analysis. An integrated isoflurane anesthetic gas system and physiologic monitoring system allow for image gating and animal monitoring during scanning.
