DXA scans can also be used to measure total body composition and fat content with a high degree of accuracy comparable to hydrostatic weighing with a few important caveats. [18] [specify] From the DXA scans, a low resolution "fat shadow" image can also be generated, which gives an overall impression of fat distribution throughout the body. [19]
Getting an InBody scan is considered to be a more affordable and convenient alternative to a DEXA scan, which uses X-ray images to measure how much muscle, fat, and bone you have. New DEXA ...
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. [5]
DXA scans assume a constant relationship between the amounts of lean soft tissue and adipose tissue. This assumption leads to measurement errors, with an impact on accuracy as well as precision. To reduce soft-tissue errors in DXA, DXL technology was developed in the late 1990s by a team of Swedish researchers led by Prof. Ragnar Kullenberg.
The commission proposes using body size or body fat measurements, such as waist-to-hip ratio or bone densitometry scan or DEXA, in addition to BMI to determine clinical versus pre-clinical obesity
Similarly, a formal body composition test, such as a dual-energy X-ray absorptiometry (DEXA) can help, says Bryant Walrod, MD, a sports medicine physician at The Ohio State University Wexner ...
