DEXA scan A DEXA scan (dual-energy X-ray absorptiometry) is the “gold standard” for calculating body composition because it’s low cost, low radiation, and very accurate, Dr. Busse says.
BMI stands for body mass index, ... DEXA scan (Dual energy/X-Ray absorptiometry). ... "Increasing muscle mass helps metabolize fat, protect bone density and restore the body to a healthy metabolic ...
Dual-energy X-ray absorptiometry is the most widely used and most thoroughly studied bone density measurement technology. The DXA scan is typically used to diagnose and follow osteoporosis , as contrasted to the nuclear bone scan , which is sensitive to certain metabolic diseases of bones in which bones are trying to heal from infections ...
Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body. Most body water is stored in muscle.
A DEXA scan requires medical supervision by a radiologist. Total body scans using DEXA give accurate and precise measurements of body composition, including bone mineral content (BMC), bone mineral density (BMD), lean tissue mass, fat tissue mass, and fractional contribution of fat.
We’ll start at the very beginning: Body mass index (BMI) is a measure of someone’s weight compared to their height whereas body fat percentage is a measure of how much body fat someone has ...

A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.
