DEXA Report

Dual energy x-ray absorptiometry (DEXA) is an innovative and advanced form of x-ray technology designed to measure body composition and bone mineral content. Scans take just 3 minutes. Reports are available immediately following the scan, meaning you can take these with you when you leave – no waiting!

A client undergoing a full body scan receives high resolution images and an easy to understand detailed report that includes:

  • Coloured DEXA body image used to visually map body fat, fat free mass and bone.
  • Measurements of total body fat, lean mass and bone mineral content
  • Measurement of fat, lean mass and bone mineral content in different regions of the body
  • Analysis of important health measures such as visceral fat (the dangerous one!), android and gynoid fat measurements
  • Comparison of your results to population health data
  • For subsequent scans, a comparison of current results compared to previous results (great for tracking changes!)

DEXA Radiation Safety

DEXA scans involve using radiation however are one of the lowest radiation dose test available. The average radiation dose for a whole body DEXA scan is 1-4μSv. The average daily background radiation exposure dose in Australian is 6-8μSv which means a whole body DEXA scan increase your exposure by 2.5 more hours per day. Common x-ray tests such as a chest x-ray is 40-50 μSv and a four hour common commercial flight is approximately 50μSv.
