Cryogen-Free 7T preclinical MRI – MRS 7000TM Series

The revolutionary MRS 7000 preclinical MRI systems are leading edge, cost-effective translational preclinical MRI instruments, providing superior soft tissue contrast and molecular imaging capability. The very compact MRS 7000 Series is almost identical in size to our revolutionary MRS 3000 Series systems, offering variable field strengths of 0.1T to 7.0T.

The cryogen-free superconducting magnets have almost no fringe field, allowing for safe use in any facility or existing laboratory and by any operator, with low running costs and no special site requirements.

The MRS 7000 MRI systems require NO LIQUID HELIUM. (Dry Magnet) The MRS 7000 series MRI systems are designed to complement and enable multi-modality imaging. Delivering powerful performance and ease-of-use. The systems are compact with a small footprint design that can be placed in close proximity to other imaging modalities.

Preclinical Applications

MouseTumorPETMRLike other preclinical modalities, MRI can monitor in vivo biological variables noninvasively, and serially track the progression of a disease or intervention in the same living animal, thus improving a study’s biological and translational relevance. MRI is without parallel in providing detailed anatomical and morphological data, for soft tissue structures. Learn more about the various applications including:

  • Brain imaging
  • Organ imaging
  • Tumor assessment
  • Disease progression assessment
  • Functional imaging
  • Investigating new contrast mechanisms and agents
  • Monitoring gene expression
  • Analyzing protein interactions
  • Determining pharmacokinetics
The System

The MRS systems are used worldwide by leading institutions for a wide range of life sciences research applications including, functional, molecular, anatomical and multi-modality imaging.

  • No special site requirements for the MRS systems.
  • Compact with a small footprint design and can be placed side-by-side with other imaging modalities.
Animal Handling

Minerve_BedMRS systems use Minerve animal handling system. Much more than a simple animal bed for preclinical imagers, the Minerve system provides a well-controlled environment for handling lab animals and plays a critical role in obtaining accurate, reproducible imaging results, while also maintaining each animal’s health and the safety of the surrounding lab environment.

How the Technology Works

The technology solution is pioneered by MR SOLUTIONS and its magnet partners.

  • Revolutionary magnet design there is no need for the expensive and cumbersome liquid helium cooling equipment.
  • Standard fridge cools solely using a standard low temperature cryo-cooler (fridge) to the required 4 degrees Kelvin (minus 269 degrees C) – needed to achieve superconductivity.
