Bone Density Scan Intro Bone density normally indicates the power of a bone and its capacity to shed weight. Carrying out a bone density scan consequently measures a bone's strength, its ability to sustain weight, and its threat of fracture. The most usual and accurate way to measure bone density would be to utilize a Dual-Energy X-ray Absorptiometry (DEXA) scan. (Medlineplus, 2014).) Prior to the use of DEXA was released, osteoporosis could be ascertained only when a patient struck a bone, and by then, the bone may have become very weak. With a bone density scan nevertheless, it may be determined if someone is at risk of bone fracture, or at risk of osteoporosis. The bone density scanning is done with Dual Energy X-ray Absorptiometry (DEXA) equipment. The DEXA technology became available for clinical use in 1987, but after that, there were the Single Photon Absorptiometry (SPA), and Dual Photon Absorptiometry (DPA), and each of which are not in use. (Dasher, Newton, & Lenchik, 2010). The bone density scan is normally performed on the following patients: • Post menopausal women not taking estrogen. • Patients with private or maternal history of hip fracture or smoking. • Post menopausal women who are tall (over 5ft 7inches), or so thin (less than 125lbs). • Guys with clinical conditions associated with bone loss. (Radiologyinfo.org, 2013). The DXA Scanner Cable, (2013), also described the DEXA scanner as a machine that generates two thirds beams of high and low energy levels. Much like fluoroscopy, the x-ray from the DEXA scanner comes from underneath the individual, along with the scanner has an extremely low x-ray dose. Earlier versions of this DEXA scanner emitted radiation which required up to 5 minutes to scan an area of attention, however the more sophisticated machines can shoot as.
