What is DEXA?
(DEXA) Dual-Energy X-Ray Absorptiometry is the most accurate
and advanced test available for measuring bone mass with
excellent resolution and reproducible precision. Mineral
radiation (less than 1/20 of a chest x-ray) is used to
determine the bone density of the spine and hip. A DEXA
test is more sensitive than ordinary x-rays, more accurate
than radiograms (radiographic absorptiometry) and can
diagnose bone loss at an earlier stage.
Safe and painless, the 10 minute DEXA scan is the most
reliable test to determine even the earliest stages of
bone loss associated with osteoporosis as well as accurate
body composition percentages and disposition.
DEXA can also determine body composition by “seeing”
fat and lean mass. Body fat distribution throughout the
body, which was not available by any method prior to DEXA
can now be accurately measured. Muscularity is also measured
and its proportional distribution throughout the body
is displayed. As an example, you can actually measure
the amount of muscle in each arm.
