1 Peripheral dual-energy X-ray absorptiometry (P-DXA). 2  P-DXA is a type of DXA test. 3  It measures the density of bones in the arms or legs, such as the wrist. 4  It can't measure the density of the bones most likely to break, such as the hip and spine.5  P-DXA machines are portable units that can be used in a doctor's office. DXA can measure as little as 2% of bone loss per year. 2  It is fast and uses very low doses of radiation. 3  Single-energy X-ray absorptiometry (SXA) may be used to measure heel and forearm bone density, but SXA is not used as often as DXA. 4  Peripheral dual-energy X-ray absorptiometry (P-DXA). 5  P-DXA is a type of DXA test.
