3 Tesla Siemens Trio Console

Installed in 2002, this standard 3T scanner is identical to those used in hospitals for clinical diagnosis. Dedicated to research use, it serves a large community of investigators, mainly for brain research that includes cognitive neurosciences, psychiatric diseases, child development, and more. Together with the CMRR's second 3T instrument, this FDA-approved scanner serves the basic and translational MRI imaging needs for researchers across the university, as well as business partners from the Twin Cities medical device industry.

3 Tesla Siemens Prisma Console

Acquired in 2012 and upgraded in 2014, this state-of-the-art 3T scanner is equipped with advanced imaging capabilities, including 128 receive channels. Together with the CMRR's first 3T instrument, this FDA-approved scanner serves the basic and translational MRI imaging needs for researchers across the university, as well as business partners from the Twin Cities medical device industry.

4 Tesla Varian Console

This 4T system is one of three models whose installation marked the beginning of high field magnetic resonance imaging and spectroscopy. Of the three, this system is the only one to have survived. Currently, it is heavily used for spectroscopy studies in human.

7 Tesla Siemens Console (Passively Shielded)

In 1999, the CMRR established the world's first 7T MRI scanner, based on a passively shielded magnet with a 90 cm bore from Magnex Scientific, which is currently part of Agilent Corp. CMRR staff performed system integration using components acquired from various vendors.

7 Tesla Siemens Console (Actively Shielded)

In 2011, the CMRR established a second 7T scanner in 2011, as 7T systems played an increasingly important role in biomedical research in both the brain and the body. It supports core research as well as collaborative and service projects.

9.4 Tesla Varian Console (65 cm Bore)

Installed in April 2004, this 9.4T system is used for large animal model studies, particularly for cardiac experiments. It is suitable for human head imaging, as well. This system was one of two installed in an effort to explore magnetic fields beyond 7T for human imaging. The other system was installed at the University of Illinois in Chicago.

10.5 Tesla Siemens Console

Currently undergoing installation, this 10.5T magnet will be the highest field whole body MRI system in the world and pioneer a new level of capabilities needed for advanced biomedical imaging. It will be used for studies of both the brain and the human torso. This revolutionary system was funded by the University of Minnesota, the State of Minnesota, and the NIH under the NCRR High End Instrumentation Grant.

Animal Systems

9.4 Tesla Varian Console (31 cm Bore)

This 9.4T system is the workhorse for animal model studies at the CMRR. It was the first such high field magnet with a horizontal bore suitable for animal model studies, pioneering the most commonly employed MRI/MRS system for animal model studies today.
