DEXA for Body Composition: BMC, FAT, LEAN

DEXA scanning is a nondestructive technology to precisely and accurately measure many parameters of whole-body composition in small animals. Originally designed for noninvasive measurement of bone density, DEXA is now also widely used for body composition measurements.

  • DEXA provides excellent reproducibility of data in both lean and obese lab animals.
  • DEXA mouse body composition measures correlate well to chemical analysis measures,  but DEXA is a much faster process and assesses body composition in vivo.
  • Body composition analysis by DEXA is based on the characteristic “signatures” of differential attenuation of low and high energy X-rays by specific tissues.
  • To analyze a particular substance (eg, BMD, BMC, FAT, LEAN), researchers work with the dual energy X-ray characteristics of the material to be analyzed in order to obtain mass values in a sample.

The software can analyze the entire composition, and specific regions of interest drawn by the end user to explore certain regions of the body.
