title: Dual-energy x-ray absorptiometry: overused, neglected, or just misunderstood?
abstract: Assessment of bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) plays a vital role in the diagnosis of osteoporosis and in monitoring a patient's response to drug therapy. This commentary will discuss controversies surrounding the use of DXA for screening and monitoring of BMD in women.
