Niumag QMR06
ECHO-MRI
ECHO-MRI for in vivo measuring lean mass, fat mass, and water content
System Overview
The Niumag QMR06 is a quantitative echo-MRI system designed specifically for awake, small laboratory animal body composition measuring. With no prior preparation or anesthetic needed, the QMR06 is effective for user friendly quantitative analysis of lean mass, fat mass, and water content. Echo-MRI quantifies these parameters based on the differences in relaxation times between lean, fat, and water. The QMR06 is ideal for mice and rats up to 800g and isolated tissue up to 6g (090H-PRO). Permanent magnet technology makes the system low maintenance and easy to operate. The QMR06 is suitable for longitudinal studies due to the non-invasive nature measurement acquisition. Additionally, there is an optional imaging mode available for capturing 2D images of fat distribution.
The QMR06 provides the following measurements:
– Lean mass (g)
– Fat mass (g)
– Water content (g)
Features & Benefits
Zero preparation required
ECHO-MRI is a no hassle method for quantifying body composition with no prior preparation needed such as anesthesia.
Non-invasive
With a non-invasive approach for body composition measurements, the QMR06 is ideal for longitudinal studies.
Awake animal measuring
Without need for anesthetic, you can measure lean mass, fat mass, and water content in awake animals.
Optional imaging mode
The QMR06 has an optional mode to acquire 2D images of the spatial distribution of fat mass.
Permanent magnet technology
With permanent magnet technology operation and maintenance is simplified with the QMR06.

Applications
Metabolic disorders occur when the normal metabolic processes within the body are disrupted, either due to genetic abnormalities, or developed due to environmental conditions.
There is a very long list of metabolic disorders, but most common are diabetes, metabolic syndrome, obesity, etc. There are many small animal models of these diseases which could benefit from ECHO-MRI to help elucidate the genetic, molecular, and biochemical pathways that contribute to these pathologies.
In this study the QMR06 was used to analyze body composition in response to diet induced obesity and the treatment Rutin.

Dietary interventions and research
Drug and therapeutic development studies are key to the progression of target compounds progressing to clinical trials. In addition to efficacy of the target compound on their intended pathology, it is also very important to study their safety and potential toxic effects, some of these effects that may be seen by studying changes in body composition. Small animal studies are routinely used for drug and therapeutic development prior to advancing to clinical trials.
The QMR06 was used in the example below to measure change in body composition in response to different antibiotic treatments.
