Central DXA: The National Osteoporosis Foundation (NOF) recommends a BMD test of the hip and spine by a central DXA machine to diagnose osteoporosis. DXA stands for dual energy x-ray absorptiometry. When testing can’t be done on the hip and spine, NOF suggests a central DXA test of the radius bone in the forearm.
Other less effective tests are -
* pDXA (peripheral dual energy x-ray absorptiometry)
* QUS (quantitative ultrasound)
* QCT (quantitative computed tomography)
* pQCT (peripheral quantitative computed tomography)
