Sherbrooke Molecular Imaging Center


Contact our TeamThe Sherbrooke Molecular Imaging Center (Centre d’imagerie moléculaire de Sherbrooke : CIMS) of the Centre de recherche du Centre hospitalier universitaire de Sherbrooke (CRCHUS) provides a unique range of pre-clinical and clinical imaging modalities to research scientists and industry partners.

The CIMS of CRCHUS has a recognized expertise in Positron Emission Tomography (PET), Magnetic Resonance Imaging (MRI), Computed Tomography (CT) and optical imaging.

From bench to bedside

With its two cyclotrons and a complete radiochemistry department, the CIMS of CRCHUS:
  • provide a wide variety of radiotracers and radiopharmaceutical products and conducts the required in vitro and in vivo validation of these agents

  • owns the infrastructure necessary to the development of pre-clinical and clinical applications for the benefit of patients.
  • is specialized in the design, the development and the operation of state-of-the-art pre-clinical scanners and biomedical instrumentation.




We produce medical radioisotopes with short half-life (carbon-11, nitrogen-13, oxygen-15) available on site as well as several other radioisotopes and radiotracers for pre-clinical and clinical research and sale.

We are specialized in radiotracer development for a wide variety of pre-clinical and clinical applications.

Our expertise in the labeling of small molecules, oligonucleotides, peptides, antibodies and proteins facilitates the translation of new radiotracers to clinical practice.

    • Production and sale of medical radioisotopes: Fluoride-18 (18F) , Copper-64 (64Cu) ,  Technetium-99m (99mTc),  Ziconium-89 (89Zr)
    • Radiolabeling of biomolecules and multimodal probes with: 11C, 18F, 64Cu, 89Zr, 124/125I.
    • In vitro and in vivo stability studies
    • Identification of metabolites



The radiochemistry laboratory houses state-of-the-art equipment, and holds an establishment license for production of radiopharmaceuticals according to certified manufacturing practices (GMP).

  • Two (2) cyclotrons: TR-19 and TR-24
  • Hot cells
  • Radiosynthesis units
  • Three (3) clean rooms
  • Analytical equipment: HPLC, UPLV, Instant ImagerTM, MS
