Viribus Unitis (Lit. “Union is strength”) is becoming more and more important to tackle the challenges of modern experimental medicine research. For this reason, in collaboration with Cardiff University and other academic institutions across the world we launched the PET Partnership UK (PPUK). PPUK is a platform built to share recourses and expertise for PET imaging. It aims to be an open and democratic community to help scientists working in PET when no local support is available.
