DEXA scans are safe, painless, non-invasive, and use a very low dose of radiation. Most scans take approximately 10 to 30 minutes.
A DEXA Body Composition Scan is a non-invasive assessment that measures the proportion and distribution of fat, muscle, bone and water in different areas of the body, including the arms, legs, and trunk. The results are highly accurate and reproducible, allows clinicians to scientifically and objectively assess the quality of weight loss rather than weight alone.
DEXA Body Composition Scans are available at Nuvo Health Double Bay and Nuvo Health Longueville.

Patients undergoing body composition monitoring may choose to repeat scans periodically throughout the year to objectively track their progress over time.
Body composition analysis may be useful for:
Monitoring muscle mass and fat distribution during weight-loss programs, especially if commencing GLP-1/GIP receptor agonist medications
Assessing sarcopenia (age-related muscle loss)
Patients undertaking preventative health or longevity programs, monitoring risk factors associated with obesity, diabetes, cardiovascular disease, and metabolic health
Tracking lean muscle gain and fat loss for fitness and athletic performance
Body composition scans use an extremely low dose of radiation (approximately 1–5 µSv), which is considered negligible and significantly lower than a standard chest X-ray or even the radiation exposure from a short airplane flight.
We recommend wearing comfortable clothing without metal zippers or buttons where possible. To ensure accuracy, avoid scheduling your DEXA scan within one week of a barium X-ray study, a nuclear medicine scan or CT scans with contrast.
You should also avoid high-dose calcium supplements for 24 hours before your scan. DEXA scans should also be avoided during pregnancy. Please inform our staff if you are pregnant or may be pregnant prior to your appointment.
During the scan, you will lie comfortably on an open scanning table while the DEXA scanner passes over your body. The procedure is painless and typically takes 10–30 minutes.
Bone density scan reports will be sent to your referring GP for interpretation and discussion
Body composition reports can be provided directly to you
For both scan types, we recommend a follow-up consultation with your GP to review your results, discuss their significance for your long-term health, and develop an appropriate management plan if required.
