On Thursday June 27th, 2019 at 5:00 AM (U.S. EST) Agilent Site Reliability Engineers will be working with our Network Service Provider to upgrade the API server for the North American instance. The entire process is expected to be 1 hour, and iLab customers using the API for any features may experience a decrease in performance during this time. More information can be found on the iLab Status Site. For any questions, please contact iLab Support at or by clicking on the 'Help' link at the top of your account page.

VUMC Institute of Imaging Science (VUIIS) - Center for Small Animal Imaging

Overview of Services

What we can do for you


Our center has in vivo and ex vivo imaging capabilities of small animals and tissue samples via magnetic resonance imaging, x-ray/X-ray CT, Positron emission (PET) and single photon emission and bioluminesence/fluorescence imaging.

We provide training for users on ultrasound and optical imaging, and provide expert instrument operators for other modalities. We also provide expert support/training for data/image analysis.





The Center for Small Animal Imaging (CSAI) is a comprehensive resource of state-of-the art biomedical imaging instruments spanning a wide range of modalities, including MRI, X-ray/X-ray CT, PET, SPECT, ultrasound, bioluminescence and fluorescence. These instruments provide a means of quantitative and radiological evaluation of pre-clinical models of disease, including cancers and numerous neurological and musculoskeletal disorders. The CSAI also serves as a primary laboratory for many VUIIS faculty who are active in the development of imaging technologies, including instrument design, molecular imaging innovation, and novel imaging characterization of tissue micro-anatomy and function.
