Full Answer

Osteoporosis is a condition where calcium is gradually lost from bones, making them more brittle and prone to breaking, according to the Radiological Society of North America. A bone density test uses X-rays to measure the amount of calcium present in a person's bones. It can also be used to monitor the effectiveness of osteoporosis treatment and assess the risk for developing fractures.
