Dual-energy X-ray absorptiometry (DXA, or DEXA ) is a means of measuring bone mineral density (BMD) using spectral imaging. Two X-ray beams, with different energy levels, are aimed at the patient's bones. When soft tissue absorption is subtracted out, the bone mineral density (BMD) can be determined from the absorption of each beam by bone. Dual-energy X-ray absorptiometry is the most widely used and most thoroughly studied bone density measurement technology. slow type gifWebDual energy X-ray absorptiometry (DXA), the most commonly used method to evaluate the BMC and BMD, is considered to be a precise technique to evaluate the body composition in children and adolescents, providing whole-body and regional estimates of the BMC, fat-free mass (FFM), and fat mass through the X-ray attenuation of the body … soh cah toa sheetWebDual-energy x-ray absorptiometry (DEXA) is the technique of choice in the assessment of bone mineral density (BMD) , the average concentration of mineral in a defined section of bone .
