Significance of Bone Density Measurements
Bone density measurements indicate the amount of calcium in the bones. One way to find the amount of calcium in the bones is to get a bone density test done. People above 50 should get a bone density test done to prevent osteoporosis.
As per the bone density measurements, the patient will be prescribed by the doctor to make diet changes, or take calcium supplements. Dual-Energy X-ray Absorptiometry (DEXA) is a pain-free and safe bone density test that is done through radiology to provide accurate and precise results.
Various other tests that are available for detecting osteoporosis are as given below:
Radiographic Absorptiometry: This test involves the use of x-rays. It is a pain free technique that works by calculating the amount of bone density that is present. Bone density measurements showing low bone density is a major indicator of Osteoporosis.
Within the spine, if you wish to measure the loss of bone matter, Quantitative Computed Tomography is the preferred method. The best advantage of this technique is its sensitivity to bone loss upon the early development of osteoporosis. However, the disadvantage is, this method is high in its radiation levels.
Quantitative Ultrasound is yet another method that uses sound waves to measure bone density. This technique directs its testing upon the spine, and also on some other targeted areas.
Another ultrasound technique used for testing osteoporosis is the Peripheral Ultrasound. Such procedure involves measuring the heels and wrists for amounts of bone density. However, this technique does not provide detailed results.
Bone density measurements are important to detect osteoporosis at an early stage.
