Dual energy x-ray absorptiometry (DEXA) is an innovative and advanced form of x-ray technology designed to measure body composition and bone mineral density. Scan times vary depending on the type of scan performed. Reports are available immediately following the scan, meaning you can take these with you when you leave – no waiting!
As an example, a client undergoing a full body scan receives high resolution images and an easy to understand detailed reports that include:
- Coloured DEXA body image used to visually map body fat, fat free mass and bone.
- Analysis of fat, lean mass and bone density measurements for total body
- Analysis of fat, lean mass and bone density measurements 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.
Women should always inform DEXA Melbourne staff if they are pregnant or possibly pregnant.
Why Hologic Horizon DEXA?
Hologic are widely regarded as the leader in DEXA technology, pioneering the first DEXA system in 1987, and in our opinion offered features and reports that would best suit our patient base.
Hologic’s new Horizon DEXA System supersedes the Hologic Discovery DEXA System.
“The same excellent features available on the Discovery have been preserved and then extended on the Horizon platform to enhance performance”. – Hologic
The latest innovations in DEXA technology available on the new Horizon units include the first units to use ceramic detectors offering crisper, higher resolution images and a multi-faceted system that can help clinicians assess bone health, body composition and cardiovascular risk.
Having a single comprehensive platform for the assessment of three major health issues: osteoporosis including vertebral fracture assessment, obesity, and cardiovascular risk as well as being able to performance advanced body composition assessments made Hologic Horizon the logical and preferred choice for DEXA Melbourne.
