Awake Small-Animal Body Composition Imaging Analyzer QMR12-060H-I

The QMR series is a specialised instrument developed by Niumag for quantitative and qualitative analysis of small-animal body composition. Using quantitative magnetic resonance (QMR) technology, it rapidly measures fat and lean mass in conscious small animals by exploiting the relaxation differences between these tissues. MRI imaging provides a direct, two-dimensional visualisation of fat distribution, which, when combined with quantitative measurements, offers comprehensive and in-depth data support for research applications.
