Short for Dual Energy X-Ray Absorptiometry, DEXA or DXA is the scientific gold standard method for assessing body composition and bone density screening. For over 30 years, DEXA has been used for Osteoporosis screening in the medical and healthcare industries where doctors collect bone density data and issue preventative medicine for their patients.
DEXA is the only tool available for bone density and with third generation technology and software; it is also the only method that will measure exact bone, fat and lean tissue content as opposed to an estimation.
Whether used for body composition or bone density, DEXA screening is applied in a quantitative analysis manner vs. diagnostic.
How Does DEXA Work?
Our system uses a narrow angle fan beam to pass two very low energy x-rays through the body, which are intercepted and detected by the detector in the c-arm, mapping your body on a pixel-by-pixel basis and generating a comprehensive snapshot of your fat, muscle and bone tissue content – in each region of your body.
The energy of the dual x-rays during a total body composition scan is minimal. We get exposed to radiation every day, from the atmosphere, from the ground, from appliances we use such as mobile phones. This is called ‘natural background radiation’.
The radiation from a total body composition scan is equivalent to less than half a day of natural background radiation.
Through our custom generated reports you will get the most valuable data, presented to you in the most meaningful way. If you have booked a consultation we will take you step by step through your results and discuss these with you. We can also look at findings of previous scans and track your progress with accuracy.
Your report will feature the following metrics.
TOTAL BODY COMPOSITION
Your DEXA scan summarizes the fat, muscle and bone tissue of your entire body. Total Body Composition Analysis shows you exactly what you’re made of.
REGIONAL BODY COMP
The regional body composition analysis shows the 5 key regions of your body including your arms, legs, trunk, android and gynoid metrics, displaying the unique composition of each.
BODY FAT PERCENTAGE
See the exact body fat percentage for your entire body as well as for each key region.
FAT TISSUE (Kgs)
With the 3 component model, you can be confident in the identification of fat tissue throughout your body. Reported in pounds for both total and regional body, plus baseline and repeat trending.
TARGET BODY FAT
The target body fat table is meant to provide general guidance for individuals based on their demographic, assist in setting goals and optimizing their training programs.
RESTING METABOLIC RATE
Your RMR metric is a nutritional baseline indicating the number of calories you should intake to sustain lean tissue and support your nutritional needs.
LEAN TISSUE (lbs)
As one of the primary DEXA components, lean tissue is identified, but not estimated. Get the exact mass, reported in pounds, for both your total and regional body analysis plus baseline trending.
BONE MINERAL CONTENT
Another key DEXA component, with impressive edge detection and precision, our system can identify and distinguish BMC from other tissue. Your BMC is essentially the weight of your entire skeleton.
BODY FAT DISTRIBUTION
Our advanced body composition analysis software is able to generate your body fat distribution analysis providing various metrics and target areas for this specific measurement.
We report on your bone density and how you compare to others like you. Bone density is essential to quality of life, especially as you surpass peak bone mass and age.
The total number of standard deviations above or below what’s considered normal for someone of your age, sex, weight and ethnicity is your Z-Score.
The muscle balance table regionalizes your arms and lets in order to assess muscle symmetry, identifying any imbalances and uncovering areas of improvement for optimal performance.
Similar to your Z-Score, your T-Score is the total number of standard deviations above or below and compared to what is normally expected in a young adult of your gender.
MUSCLE MASS TRENDING
Just like we can with your fat mass, we’re able to pinpoint each region’s muscle mass, track and trend your fluctuations over time in response to your training regimens.
BODY FAT TRENDING
We’re able to pinpoint each regions body fat mass, track and trend your fluctuations over time in response to your training regimens.
With our ability to report on this metabolic health metric, Relative Skeletal Muscle Index can be used to assess the lean/fat distribution in your arms and legs as well as degenerative muscle loss.
Android is the lower abdominal area of your trunk and Android fat is associated with visceral or unhealthy fat. Ideally, Android fat tissue % should be less than your total body fat %.
Gynoid fat is concentrated in the hips, upper thighs and buttocks regions of your body. It’s not necessarily unhealthy, but is one area where we as humans naturally store excess fat.
The Android / Gynoid ratio (A/G) compares your Android fat to your Gynoid fat as part of our body fat distribution analysis. For ideal fat distribution, the A/G ratio should be less than 1.0.
Unlike alternative body fat testing methods, our DEXA system can colour code and map images enabling you to understand your body and visualize changes over time.
