7T MRI Facility
The 7T Facility is located on the basement level of the Nutrition Research Building. This facility houses a Bruker Biospin 7T microMRI scanner.
John Olson, MS is the Coordinator of the Small Animal Imaging Facility. MR techniques currently available on this scanner include:
In vivo mouse, rat, and non-human primate imaging with sub 0.1mm resolution
Magnetically labeled cell tracking
Mouse and rat cardiac and atherosclerosis imaging
Proton Spectroscopy
Diffusion Tensor Imaging
7T Bruker microMR Scanner
Superconducting Magnet System
Actively-shielded superconducting wide-bore magnet
Nitrogen free (no cryogenic maintenance by customer)
Cryo-refrigerator (Minimal helium consumption, long hold-times, long maintenance intervals)
Reduced stray field
Screening against external field perturbations
