What is DEXA?

Dual Energy X-Ray Absorptiometry, also known as DEXA, is the preferred technique for measuring bone mineral density (BMD) and for Total Body Composition analysis (TBC). This is because a DEXA scanner uses an enhanced form of low dose x-ray technology to detect bone loss or changes in the body’s soft tissue composition (muscle mass and fat mass). The machine produces two precisely calibrated X-ray beams, each with differing energy levels. The amount of attenuation of the X-ray beams by the bone, fat and muscles is measured for each beam. The result is a three component scan that measures fat, lean muscle and bone density with 99% accuracy. And the reason why DEXA is the preferred method is that the level of radiation is so low (approximately 5 microSv) that you exposed to more radiation from natural sources, in an average day.

Accuracy

DEXA body composition scans are highly reproducible, accurate and precise. This means you can track your progress with confidence. Our technicians have been trained, and we believe that our standard operating procedures for Body Composition work is at the highest technical levels. Each aspect of our approach is backed by many hours of research and consideration of best practices. In this way, you can be confident that each DEXA scan will provide the following information with 99% accuracy:

  • Total body bone mineral density
  • Total body muscle mass (kg) and Lean Mass Index
  • Total body fat mass (kg) and Fat Mass Index (FMI)
  • Total body fat percentage
  • Muscle and fat mass of the trunk and each of your arms and legs
  • Central abdominal fat measurement (visceral adipose tissue)

You may be interested in a DEXA scan if you:

  • Have a family history of osteoporosis
  • Are frustrated with measuring yourself with ordinary scales
  • Want an accurate baseline before commencing a fitness or weight loss program
  • Aren’t getting the best results out of your diet
  • Are curious whether you have gained muscle
  • Want to know how much dangerous visceral adipose tissue (fat around your organs) you have
  • Want to know how your percentage fat and lean mass compare with other people your age, and healthy reference values
  • Have a BMI in the “overweight” range, but think that it may be overestimated by extra muscle mass
  • Want to know which areas of your body have the most muscle mass and fat mass
