What is DEXA?

Dual-Energy X-Ray Absorptiometry (DEXA) combines two X-Ray beams with different energy levels to measure a patient's bone mineral density (BMD). No special preparation is required.


The machine can also be used to generate a total body composition report, which is useful for monitoring muscle bulk and fat content and observing any changes following a new treatment or training regimen.

A DEXA body composition report will accurately measure fat, bone and muscle mass for total body regions, allowing you to target your fitness and training program for optimal results.

Your body composition scan will include:

  • total body bone mineral density (BMD)
  • total bone mineral content (BMC)
  • fat mass
  • lean mass
  • percentage fat.

Medicare rebates are available for DEXA BMD studies based on the following criteria:
