Easily Understand How To Test Bone Density with the Help of Modern Scanning Technologies
It is not too difficult to know how to test bone density after the emergence of many modern and advanced medical technologies. The bone mineral density test refers to the best way to identify and determine the health of bones. This test can easily identify the bone problems by applying dual-energy x-ray absorptiometry, or DXA test that uses x-ray to measure bone density. In the medical term, bone density refers to the amount of matter per centimeter of bones. Such test involves the least amount of exposure to radiation.
There are different types of BMD tests, and all are non-invasive. These tests include dual energy x-ray absorptiometry, quantitative computer tomography, qualitative ultrasound, single photon absorptiometry, dual photon absorptiometry, digital x-ray radiogrammetry and single energy x-ray absorptiometry. Through these technologies one can understand how to test bone density perfectly.
The DEXA scan can deliver most accurate bone density test and can detect even 1 percent change in bone density. This type of scanning takes about 10 minutes and exposes the patient to an amount of radiation that is less than during a chest x-ray. During the DEXA test, a person lies in bed under the scanner and a plastic arm radiates x-rays. The images of the person’s body taken by the scanner are subject to comparison of the patient’s bone strength. The results of the test are reported in terms of three parameters such as Z-score, T-score and the density measured in grams per cubic centimeter. Overall, it is very easy to understand how to test bone density with the excellent tool in the diagnosis of osteoporosis. Although no bone density test is 100 percent accurate, and in this regard the DXA test is the single most important predictor of whether a person will have a fracture in the future.
