Dual Energy X-ray Absorptiometry (DEXA)
- Bone Density Test
- Bone Density Measurement (osteoporosis)
|
- Osteoporosis is a disorder of the bones characterized by a progressive loss of bone tissue, the result of which is an increase in the risk of fractures, often from minor falls or spills that would not normally result in a fracture.
- A routine x-ray examination can reveal osteoporosis, but by the time this can be detected using conventional x-ray, the disease may have progressed significantly. Fortunately, other tests are available to diganose the disease in earlier stages so that treatment can begin.
- The best technique currently available in measuring bone mass is dual energy x-ray absorptiometry (DEXA). This test measures the bone masss in two important areas: the hip and the spine.
- The test is painless and simple to conduct and usually takes less than ten minutes.
- Dexa is very safe -- the radiation is minimal and the test is very precise.
- DEXA is also useful in tracking the progression of osteoporosis.
- Patient preparation: No calcium supplements the day of the exam.
