How is a Bone Density Test Performed?
Bone density, commonly known as bone mineral density (BMD), refers to the level of matter per cubic centimeter in your bones. As we age, our bones naturally become thinner and our existing bones break down before our bodies can regenerate new bone mass. As a result, our bones become lighter and more porous due to a loss of calcium and other minerals. A bone density test is performed to diagnose possible osteoporosis, bone strength and risk of fracture. The two most common tests, currently used to measure bone mineral density (BMD), are the energy X-ray absorptiometry and qualitative computed tomography procedures. All bone density tests are non-invasive and painless and have very low levels of exposure to radiation.
