What is a DXA scan?
Dual-energy X-ray Absorptiometry (DXA) uses small amounts of x-ray to measure your body composition. A DXA scan can be used to
- quantify and locate Body Fat% and Lean Muscle Mass% in your body;
- measure bone mineral density; and
- monitor bone density and body composition trends serially.
This scan is FDA approved to quantify the deep, dangerous fat that is around your organs, known as visceral adipose tissue (VAT). VAT is linked to a number of health problems like type-2 diabetes, cardiovascular diseases, and cancer.
How should I prepare?
A prior requirement is to avoid Calcium supplements 24 hours before a DXA scan. It is also recommended to have a lighter meal or be fasted before coming in.
You will be asked to change into a gown and any zips, hooks, jewelry, or buckles need to be removed.
What can I expect?
You will lie down on a table and during the scan, a scanning arm will be passed over your body. The whole process typically takes less than 10 minutes.
At the end of the scan, you will receive a report like the one below.
