VOA慢速英语 骨质疏松症增加骨折风险

　　VOICE TWO:

　　Before people develop osteoporosis, they have a condition called osteopenia. Treatment can prevent this condition from becoming osteoporosis. Doctors agree that the best way to deal with osteopenia or osteoporosis is to find and treat it before the disease progresses. Bone damage need not be permanent. Drugs can help replace lost bone.

　　Identification of osteoporosis and osteopenia is made by measuring the mineral density of a person's bones. In this case, density means the strength of the bones.

　　VOICE ONE:

　　The American Academy of Orthopaedic Surgeons says there are a number of ways bone mineral density can be measured. The group suggests bone mineral density examinations for women sixty years and older. Doctors use the tests to examine the hip and spine, or backbone.

　　The NOF says a test called Dual-energy X-ray absorptiometry, or DXA, is the best test for osteoporosis. DXA uses radiation from x-rays. The patient does not get much radiation from the process, which lasts only a few minutes.
