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. Dual-energy X-ray absorptiometry (DXA). 2  This is the most accurate way to measure bone density. 3  It uses two different X-ray beams to estimate bone density in your spine and hip. 4  Strong, dense bones allow less of the X-ray beam to pass through them.
