The Yale Positron Emission Tomography (PET) CenterThe PET center was built in 2005 to advance molecular imaging research at the University. The Center occupies ca. 20,000 square feet of newly constructed space and has two scanners: a CTI HR+ and a HRRT scanner, along with space for a dedicated animal PET scanner. It has a state-of-the-art radiochemistry facility that will permit the development and use of a complete line of PET radiopharmaceuticals labeled with the most common PET isotopes: 11C, 15O, 13N, and 18F. The Center also has a PET physics and data analysis group to provide training and consultation to DERC investigators.
