Medical Imaging Center (MIC)

Multi-modality imaging facilities from the departments of Radiology and Nuclear Medicine. Facility
Multi-modality imaging facilities from the departments of Radiology and Nuclear Medicine.
The MIC provides the medical imaging infrastructure and support for state-of-the-art research, ranging from preclinical studies to clinical trials. We offer extensive multidisciplinary expertise on medical imaging techniques such as PET, SPECT, CT, and MRI scanning in order to support researchers from the University Medical Centre Groningen (UMCG), the University of Groningen (UG), and external partners.
  • Molecular PET and SPECT imaging allows the visualization and quantification of physiological processes in the body by injecting a radioactively labelled tracer and monitoring its distribution with a dedicated scanner.
  • MRI scanners use a strong magnetic field and short radio waves to generate images of structures in the body. Some MRI procedures can generate information about tissue function.
  • CT scanners use X-rays to generate images of the body based on tissue density. Contrast agents may be used for MRI and CT scans.

How to use our equipment

Before you can start using our equipment and facilities, your project has to be evaluated by an internal committee. Please contact our MIC Project Management Office for further information.

We always evaluate new requests. Before you can start using our equipment or facilities, we will make an arrangement. Our assigned instructors will provide training, if necessary.

  • The MIC provides advanced imaging equipment and facilities to allow cutting-edge preclinical and clinical research to be performed. In addition, support can be offered to researchers, which enables them to get the most out of their studies. For this purpose, a range of services can be offered, including:

    • Advice on how to optimize imaging techniques, procedures, and study design;
    • Implementation of clinical imaging procedures;
    • Making or training for making preclinical scans;
    • Development and validation of tracers;
    • Data management support;
    • Data transfer;
    • Data analysis training and support;
    • Project management;
    • Contract research.

    • Extensive experience with studies for pharmaceutical industries;
    • Close collaboration with nearby Contract Research Organizations;

    • For more information, please contact:

    • Researchers are advised to contact an MIC staff member (to be found on the website footer) to discuss the optimal imaging procedures for the research question at hand.
    • The definitive or draft study protocol and the completed MIC application form have to be sent to the MIC for review. For studies with complex imaging procedures, researchers are advised to send the study protocol to the MIC before submitting it to the Medical Ethics Review Board (METc).
    • Clinical studies involving imaging procedures or interventions at the MIC will be reviewed by the Research Advisory Committee (RAC).
    • The RAC will particularly assess the suitability of the proposed imaging modality, the feasibility of the requested procedures, and the available capacity.
    • After review by the RAC has taken place, a letter of agreement that includes the tariffs will be sent to the investigator.
    • The investigator must send the definitive study protocol, the local feasibility (if applicable), and the approval letter from the METc to the MIC before the start of the study.
    •  For imaging procedures that do not meet the appropriate standard of care, a kick-off meeting with relevant MIC staff members must be organized by the principal investigator.

    • The MIC’s small animal imaging equipment (PET, PET/CT, and PET/MRI) is located in the GronSAI facility on the premises of the UMCG’s Central Animal Facilities (CDP).
    • For advice on preclinical imaging procedures and study design, please contact Dr Janine Doorduin
    • Before reservations for the preclinical imaging equipment can be made, the protocols from the Animal Experiments Committee (CCD) and the Animal Welfare Body (IvD) must be sent to Dr Janine Doorduin  and Ing Jurgen W.A. Sijbesma. Researchers are advised to send the draft protocols for review to the MIC before submitting them as CCD and IvD protocols to avoid unnecessary amendments.
    • For individual training in the use of preclinical imaging equipment and experimental procedures, please contact Ing Jurgen W.A. Sijbesma.
    • For making reservations for the use of preclinical imaging equipment, please contact Ing Jurgen W.A. Sijbesma

    • The MIC can provide training in and assistance with data management and storage of imaging and associated data.
    • The MIC can help to anonymize and transfer scans to external parties.
    • Advanced imaging procedures often require sophisticated data analysis with dedicated software packages. The MIC can offer advice about data analysis methodology and train researchers in performing analyses.
    • For assistance with data management, data transfer, and data analysis, please contact the Project Management Office.

  • For our services, a fee will be charged that depends on the type of procedures and services requested. Therefore, it is highly recommended that you contact the MIC to discuss the expected costs before signing a contract, submitting a grant proposal, or initiating a new study.
