Mouse densitometer

The PIXImus Densitometer provides bone mineral and body composition results from total body imaging of the mouse in under five minutes. Fast imaging allows use of milder sedation that is safer on animals.

The PIXImus allows accurate and precise measurement of bone and tissue for small animals 10-50 g (eg, mice, lemmings). This measured bone exhibits good correlation to total ashed weight (r = 0.99). PIXImus uses a lower x-ray energy than that used for peripheral densitometry in humans in order to achieve contrast in the extremely low density bone. Precision of bone mineral density (BMD) and %fat makes PIXImus suitable for longitudinal studies. The standard total body focuses on the active bone area in the subcranial region. There are manual ROIs for selected regions within the total body image, such as spine and femur.
