Total Body Composition Measurement
Total Body Composition Measurement Explained
Total Body Composition Measurement with Dual Energy X-ray Absorptiometry (DEXA) can look beyond weight and the traditional Body Mass Index (BMI) to determine accurate body fat distribution, muscle and bone mass.
Body composition measurements provide important information for management of many diseases, including anorexia nervosa, growth hormone deficiency, chronic obstructive pulmonary disease (COPD) and paralysis. Total Body Composition Measurement also empowers athletes and personal trainers to make effective decisions on the training regimens they use to achieve best performance and monitor the effects of diet or exercise.
Please advise us beforehand
As a very small dose of radiation is used in a DEXA scan, please advise us if you are, or think you may be, pregnant. Please also advise if you have had any recent spinal surgery or other tests using contrast media.
Please advise us if you are, or think you may be, pregnant.
Please bring your referral, Medicare and/or Pension Health Care Card and any previous imaging relating to the region being scanned.
You may be required to remove jewellery and clothing that contain zips or metal objects, as these items can interfere with the X-ray quality.
To prepare for your test it is important to have only a light meal, and no physical exercise beforehand.
You should stop taking calcium supplements for at least 24 hours before your exam.
What happens during the procedure
When you arrive, your height and weight will be measured to allow information to be generated about your bone density.
You will be asked to lay on a padded table. There is an X-ray generator located below and an imaging device positioned above.
To image your spine, your legs will be placed on a padded box. To image your hip, your foot will be placed in a brace in order to rotate your hip inward. During both processes, the imaging device will slowly pass over the area. It is very important you remain very still throughout this process.
Tests for your fingers, hand, foot and forearm are done simply by placing them in a small device to obtain a bone density reading.
How long does it take?A Total Body Composition Measurement takes approximately 15 minutes.
After Your Examination
There are no restrictions after having a Total Body Composition Measurement.

BODY COMPOSITION TREND
Scans can be compared to see exactly how your body has changed.
BODY MASS INDEX (BMI)
BMI does not distinguish between fat and lean weight. Therefore BMI is not a good indicator of ideal body weight for individuals with above average lean muscle mass.
It is important that you return to your doctor with your examination results. Whether they are normal or abnormal, your doctor needs to know promptly so that a management plan can be formulated.
