Body Composition Analysis

Cenegenics uses the GE Lunar Prodigy Advance to perform the body composition analysis.

Large scan window 6′ 5.76″ x 1′ 11.6″ (197.5 cm x 60.0 cm) supports measurement of a wide range of patient body types and wide table bed; Table bed width helps technicians to easily position patients and enhances patient comfort..

High arm height helps to accurately measure patients with a supine abdominal thickness up to 1′ 4.54″ (42 cm)

350 Ibs (159kg) Table weight limit; Table weight limit allows accurate assessment of patients up to 350 Ibs (159kg).

Accessible table height; Low table height allows ease of access for patients – easy on, easy off. Helps to minimize the stress of getting an exam.

Low Dose: Compared to other x-ray procedures, the radiation dose from DXA assessments is relatively low. DXA technology requires minimal radiation to generate measurements of body composition. However, when compared to other manufacturers of DXA devices, GE Lunar iDXA and Prodigy densitometers perform scans at a lower dose1, while still achieving higher precision

Body composition by DXA is the “gold standard.”

Precise and accurate data on tissue composition in 10 minutes

Body composition scans with DXA provide precise and accurate data on tissue composition, including lean mass and fat mass. Scans provide both total body data and regional results, including arms, legs, trunk and android/gynoid regions. Android fat is in the belly area and when it predominates, represents the “apple” shape associated with an increased risk of heart disease, diabetes and Alzheimer’s disease. The gynoid region is the hips and upper thighs where women tend to accumulate fat. A preponderance of fat here is referred to as the “pear” shape which is associated with a reduced risk of heart disease, etc.

The measurements are fast and non invasive, with the average scan completed in 10 minutes.

Looking beyond the bathroom scale

Accurate measurement of body composition provides valuable information for assessing and monitoring the progress of nutrition and training interventions. While monitoring one’s weight is helpful, it is at best a crude and imprecise way to assess results. Impedance scales and hand held devices are fraught with error. Values can vary as much as 5% in a single day based on time of day, hydration, if you are sweaty or damp, etc. Skin fold measurements are very inaccurate as well.

Body composition measurement by DXA can look beyond weight, the traditional body mass index (BMI), impedance devices and fat calipers to accurately determine body fat, as well as how that fat is distributed.

What about athletes? | Monitoring athletes’ body composition is easier now than ever: Trending capability allows direct comparison of total and regional tissue. Results help athletes make decisions on the training regimens they use to achieve the best performance. For highly trained athletes, even a small change in body composition can significantly affect performance. Body composition monitoring provides valuable information that athletes and their trainers can use to adjust diet and training regimens. Body composition measurement helps establish a starting point and a target, helping any athlete to pursue a specific goal. Some training regimens, especially for endurance athletes, can lead to muscle loss and a decrease in performance. Monitoring fat and muscle mass can shed light on how various training regimens and nutritional interventions impact body composition and performance.

DXA is an ideal way for all types of athletes – cyclists, triathletes, body builders and other fitness enthusiasts – to monitor their progress.

Understanding the Bone Density Scan

A bone densitometry test helps your physician to diagnose osteoporosis. The test compares your Bone Mineral Density (BMD) to that of a “young adult” at peak bone strength. This is displayed as your T-score. It also compares your results to people of your same age, called “age matched” displayed as your Z-score.

  • Normal: T-score that is above -1
  • Osteopenic: T-score between -1 and -2.5 (low bone density)
  • Osteoporosis: T score below -2.5

Body Composition

  • Lean Mass: Includes all parts of the body (organs, muscle & fluids) but excludes body fat
  • Fat Mass and Body Fat Percentage: Tells more about your overall fitness than just weight alone, regional fat distribution tells where body fat is located.
    • Android Fat: fat associated with apple-shaped body types. This is a measure of visceral fat or the fat located around your organs and essential fat.
    • Gynoid Fat: fat often associated with pear-shaped body types or fat located around the hips and thighs.
  • A/G Ratio: Ideally this ratio should be below 1.0. This is directly related to the prevalence of visceral fat, which is the fat insulating the organs

The factors that influence fat distribution are somewhat controllable by YOU. Fat distribution is influenced by hormones, genetics, and race, the presence of toxins, physical activity, malnutrition and stress. Controlling the amount of toxins you are exposed too, exercise, healthy eating and the amount of stress in your life is all controlled by you.
