Amenorrhoeic athletes are referred for tests, which can include measuring bone density.
Hologic Inc., a maker of devices that measure bone density, agreed to buy the United States assets of the Trex Medical Corporation, a medical imaging manufacturer, for $55 million to expand sales of women's health care equipment.
In selling an exam table that doubles as a device to measure bone density, G.E. trumpets the system's potential revenue: $30,000 a year if a doctor sees five patients a week.
The widespread availability of dual-energy X-ray absorptiometry machines to measure bone density reinforces what has been called "the tyranny of the T score," or the reference point for evaluation of osteoporosis or osteopenia.
Its role in health care is technical: G.E. makes and sells medical devices, like machines that measure bone density and perform M.R.I. scans.
You can measure bone density with a test called Dexa [Dual Energy X-ray Absorptiometry], a painless, non-invasive test.
In addition, we assessed bone quality of the supporting bone directly beneath the implants by measuring bone density and porosity.
Multiple modalities of measuring bone density have been described and validated, including dual X-ray absorptiometry (DEXA), plain radiographs and quantitative computed tomography [20].
Osteopenia and osteoporosis, mildly and severely reduced bone mineral density, are often present in people with coeliac disease, and investigations to measure bone density may be performed at diagnosis, such as dual energy X-ray absorptiometry (DXA) scanning, to identify risk of fracture and need for bone protection medication.
