Total body composition analysis using
DEXA provides the most highly accurate method of non-invasive
measurement of skeletal bone status, as well as lean and
fat tissue components including percent fat, lean tissue
mass, etc.
The accurate measurement of total as
well as regional bone and tissue composition has
relevance in a number of clinical conditions, as well as
for those health and fitness enthusiasts who wish to
monitor the effectiveness of their training regimes.

Total Body BMD and body composition are
valuable tools in
the management of clinical disorders. In addition, regional
fat distribution is clinically useful in relation to
assessing cardiovascular disease risk, glucose metabolism, and insulin
resistance.
By understanding how your muscle, fat, and bone
react to lifestyle changes, you’ll be able to improve weight
loss, create a highly targeted exercise program, and reduce
your chance of heart disease, diabetes, high blood pressure
and obesity. So how does it work?
A fine, very low-dose x-ray beam is passed through the body
to a detector array, and the resultant attenuation using dual
energy filtering provides exceptionally accurate measurement
of bone, muscle and fat. By repeating the scan every three or
six months (depending on your requirements), you can track
your progress with certainty. Just knowing exactly
how you are doing provides the best motivation you can get!
Dr Jarrod Meerkin
is an experienced Exercise
Physiologist with a Ph.D. from Queensland University of
Technology, a Masters degree (with honours) and a Bachelor of
Applied Science from the
University of
Wollongong.
During his research
on exercise and obesity, Dr. Meerkin observed the
psychological effect pre and post DEXA imaging had on patients
pursuing lifestyle changes. While a patient’s scales can
indicate a loss of weight, DEXA was able to enhance these
results by showing the effect of the weight loss on the soft
tissues of the body. For example, DEXA showed that a net
weight loss of 3 kilos included a 7 kilo reduction in adipose
(fat) tissue and a 4 kilo gain in muscle. By understanding
their body’s response to exercise, patients were able to
tailor their workouts to fit their lifestyle goals and see
greater results sooner. With more reward for their
efforts, patients were inspired to continue.
Using DEXA to determine the proportion of lean
body mass (muscle) versus total body fat is a valuable
clinical tool in the management of long-term health and
fitness. By assessing changes in body composition over time,
professional and recreational athletes are able to customise
their training to achieve specific physiological goals, and
develop tailored sports injury management plans.
For those seeking lifestyle changes and weight
loss, DEXA body composition measurements provide accurate
exercise effectiveness assessments and soft tissue analysis.
With a greater understanding of how your body is responding to
the changes made, patients are more inspired to persist with
and maintain their newly adopted lifestyle.
With DEXA you can analyse the
composition of your whole body, or that of a defined region,
such as an arm, both legs, or your torso. Undergoing a full
body DEXA scan is as simple as lying on a table for around 3
minutes. You stay fully clothed throughout the
process, and the non-invasive scan is completely pain free.
The use and safety of
DEXA is well proven. More than 70% of
pharmaceutical
clinical trials currently utilise DEXA
technology, while DEXA body composition assessment is proving
highly beneficial in advanced clinical weight loss trials.
To date, over 2000 research papers have
used DEXA for body composition assessment purposes.
DEXA results are also commonly used to show
intermediate outcomes in many Nutrition and Metabolic Disorder
studies. This widespread acceptance has helped DEXA technology
achieve a gold standard for ease of use, accuracy and test /
retest repeatability.
FAQ's
Q: "How much radiation do I get from
a total body composition scan?"
A: The quick answer is an insignificant
amount. We get exposed to radiation every day, from the
atmosphere, from the ground - even talcum powder gives off a
tiny amount of radiation. 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.

Q: "Do I need a referral for
a total body composition scan?"
A: A referral is not required - just
call up and book in!

Q: "What about Body Mass Index (BMI)
measurements - are they accurate"?
A: Check out the two men featured
below with the same BMI, and judge for yourself! Only DEXA
Body Composition can give you the answers you really need.
The man on the left has 13% body fat; the man on the right
26.3%. Same BMI, twice the body fat! The man on the left is a
body builder. The most exercise the man on the right does is
lifting his beer glass!
