Osteoporosis is a leading cause of disability among older people, particularly elderly women. Bones weakened by mineral loss are prone to fractures, especially in the spine and hip. Low bone density is measured by a number of techniques. These techniques all measure bone mineralization and detect osteoporosis or bone loss due to menopause, medications or other risk factors. DEXA (dual-energy x-ray absorptiometry) scan is one of the most widely used detectors of bone mineral density. The use of low dose radiation in conjunction with highly sophisticated computerized analysis provides unique and accurate information about bone density. One of our board-certified radiologists will interpret the results. Your test results will assist your physician in determining if treatment for bone loss is necessary.
