Body Fat Analysis (a.k.a. Body Composition) with DXA

Hologic's Discovery scanner is fast!

Most people now understand that to have a healthier body means to have a leaner body. These people are ready for Body Fat Analysis (BFA). Currently, this test does require a doctor's order as it utilizes a small amount of x-ray.

A relatively new technology that is very accurate and precise, DXA is based on a three-compartment model that divides the body into total body mineral, fat-free soft (lean) mass, and fat tissue mass. This technique is based on the assumption that bone mineral content is directly proportional to the amount of photon energy absorbed by the bone being studied.

The scanner passes across a person's reclining body and collects data. A scan takes between 10-20 minutes. It is safe and noninvasive with little burden to the individual, although a person must lie still throughout the procedure. The best results are achieved when patients change into a gown in order to prevent any false readings from snaps/zippers etc. in the clothing.

DXA is fast becoming the new "gold standard" for body fat analysis because it provides a higher degree of precision in only one measurement and has the ability to show exactly where fat is distributed throughout the body. It is very reliable and its results extremely repeatable; in addition, the method is safe and presents little burden to the patient.
