9.4T/31 cm bore MRI

Description

The 9.4T animal scanner was the world’s first ultrahigh field system established at CMRR decades ago. It was recently upgraded to replace the outdated Varian console by the Bruker console as funded by the NIH high-end instrument grant (S10OD032192). It serves the basic and preclinical MRI, MRS, and MRS/I needs for research across the university as well as supporting national and international collaboration projects.
