Bone density testing is recommended for older women whose risk of breaking a bone is the same or greater than that of a 65‑year‑old white woman with no risk factors other than age.
Older women aren't the only ones who need a bone density test. Younger women who have a fracture risk that’s similar to women who are 65 and up should also get tested.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

But because bone density decreases with age, more people become osteoporotic with increasing age. [ 4 ] :58 The World Health Organization has established the following diagnostic guidelines: [ 4 ] [ 27 ]
Bone densities are often given to patients as a T score or a Z score. A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower.
The two most common techniques for estimating bone age are based on a posterior-anterior x-ray of a patient's left hand, fingers, and wrist. [5] [17] The reason for imaging only the left hand and wrist are that a hand is easily x-rayed with minimal radiation [18] and shows many bones in a single view. [19]
