MNORC can measure body composition across the lifespan with several non-invasive methods. Dual-energy X-ray absorptiometry (DXA) utilizes a very low level of radiation (less than that to which you are exposed on a flight from east to west coast of the US) and requires that participants remain still on an open table for about twenty minutes. It provides a three-compartment model of body composition (fat mass, bone mass, lean mass) as well as regional composition (i.e. trunk, ,arms, legs, etc.). We have successfully tested babies through elderly individuals.
If you would prefer a radiation-free option and/or one that does not require that participants remain still for quite as long, MNORC also measures body composition via air-displacement plethysmography. In this two-compartment model of body composition (fat mass, fat-free mass), participants sit in an enclosed system with a large window for only a few minutes at a time. We can assess newborns and infants (1kg – 8kg body weight) in our PEA POD, toddlers and young children in our BOD POD with the assistance of pediatric attachments (similar to a high-chair) and children through older adults in the standard BOD POD system.
Our DXA is located within MCRU on Level 1 of the CVC, the BOD POD is located in Lobby M of Domino’s Farms, and the PEA POD is located near the NICU in Mott. Unsure which method is best for your study and/or want additional information? Contact us and we’ll help!
