A DXA scan is a low-dose x-ray. In fact, total radiation exposure is less than a daily dose from environmental sources. The DXA scan procedure is relatively quick and generally takes less than seven minutes (depending on body size).
The individual being tested remains fully clothed and lies still in a supine position for the duration of the x-ray. At the end of the study, a technician will provide you with a printout of your results. Results from alternatives to DXA scanning are often misleading, as these measurements are not able to distinguish several factors: gender, age, and obesity or leanness of muscular individuals. Also, other instruments are not able to provide regional body fat values. The bold and underlined portion is what is elevating DXA above the once considered "gold standard" in testing: hydrodensitometry (underwater weighing). I've attached a printout of what will be provided upon a DXA scan. Also, here's in interesting study involving adult female swimmers demonstrating the intricate nature of DXA scanning.
