A diagnosis is usually done using a combination of a complete
medical history and physical examination, skeletal X-rays,
bone densitometry and specialized laboratory tests. If you
have low bone mass, your doctor will perform additional tests
to rule out the possibility of other diseases that can cause
bone loss, including osteomalacia (a vitamin D deficiency)
or hyperparathyroidism (overactivity of the parathyroid glands).
Bone densitometry is a safe, painless X-ray
technique that compares your bone density to the peak bone
density that of someone of your same sex.
The most common diagnostic tool is a bone
mineral density (BMD) test. This is a painless and noninvasive
scan which, depending on the technology, measures bone density
in the hip, spine, wrist, heel or hand.
Several types of bone densitometry are used
today to detect bone loss in different areas of the body.
Dual Beam X-ray Absorptiometry (DXA) is one of the most accurate
methods, but other techniques may also identify osteoporosis,
including Single Photon Absorptiometry (SPA), Quantitative
Computed Tomography (QCT), Peripheral Dual Energy X-ray Absorptiometry,
Single-Energy X-Ray Absorptiometry, Radiographic Absorptometry
and Quantitative Ultrasound (QUS). |
