ICMI, the In Vivo Cellular and Molecular Imaging Core Facility at the Vrije Universiteit Brussel is specialized in nuclear and optical imaging of small animals. The lab is equipped with a myriad of state-of-the art multi-modality cameras and ex vivo analysis techniques to study tracer biodistribution, pharmacokinetics, dosimetry, and therapeutic efficacy of (radio)pharmaceuticals. The latest addition in the fee-for-services range is the imaging of living cells, while they are in a true and complex environment, using intravital microscopy.
