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
