The Nuclear Imaging platform offers state-of-the-art imaging resources in Positron Emission Tomography (PET), Single Photon Emission Computerized Tomography (SPECT), Computerized Tomography (CT) and Optical Tomography. It is equipped with small animal dedicated SPECT-CT (microSPECZT-Visio 140) and PET-CT (Explore Vista-CT) cameras and with an optical imaging system. The platform is designed to perform in vivo studies from various imaging modalities in an interleaved fashion from the same animal. The combination of these potent and non-invasive imaging techniques facilitates performing multimodal approaches to biological, physiological and medical problems, obtaining images with significant functional and anatomical information. The platform is furthermore equipped with an autoradiography system for end point-high resolution nuclear imaging.
