Dual-Energy X-Ray Absorptiometry (DEXA)
Principle of DEXA
DEXA, also known as dual-energy X-ray absorptiometry, is a widely used method to measure body composition. The principle behind DEXA is based on the fact that different tissues in the body have varying levels of X-ray attenuations. This allows DEXA to differentiate between lean tissue, fat tissue, and bone tissue.
How DEXA works
During a DEXA scan, you lie on a table while an X-ray arm passes over your body. This arm emits two X-ray beams of different energy levels, which are absorbed differently by the tissues in your body. The amount of X-rays absorbed by each tissue is measured by a detector on the other side of your body. By analyzing the differences in X-ray attenuation, DEXA can accurately determine your body composition.
Advantages of DEXA
DEXA offers several advantages as a method for measuring body composition. Firstly, it provides detailed information about the distribution of fat and lean tissue in different regions of the body. This helps in assessing the overall health and risk factors associated with excess fat accumulation. Additionally, DEXA is a non-invasive procedure that is relatively quick and painless. It also exposes you to a very low level of radiation, which is considered safe.
Limitations of DEXA
Although DEXA is a highly accurate method, it does have some limitations. One limitation is that it cannot differentiate between types of fat, such as visceral fat and subcutaneous fat. This information is important as visceral fat, which surrounds internal organs, is associated with higher health risks. Another limitation is that a DEXA scan may not provide accurate results for individuals with certain medical conditions or those who have metal implants.
Bioelectrical Impedance Analysis (BIA)
Principle of BIA
Bioelectrical impedance analysis (BIA) is a method that measures body composition based on the conduction of electrical signals through the body. The principle behind BIA is that lean tissue, which contains more water and electrolytes, conducts electrical signals better than fat tissue, which contains less water.
How BIA works
To perform a BIA measurement, electrodes are attached to different parts of your body, typically your hands and feet. A low-level electrical current is passed through your body, and the resistance encountered by the current is measured. This resistance, combined with other factors such as your age, height, weight, and gender, is used to calculate your body composition.
