Osteopenia and osteoporosis, diseases that reduce bone density and cause brittle bones, affect more than half of all women over 50 in America. For women in this age group, we highly recommend bone density testing. The earlier the detection of bone loss, the more bone density there is to save. This means a greater chance of living a full life even with osteoporosis, an otherwise crippling and debilitating disease.

Carlos & Parnell, M.D., P.A. uses an advanced x-ray system which is used to determine the extent of bone loss and assess a patient’s risk of osteoporosis by measuring bone mineral density (BMD). It is most commonly performed on the lower spine and

hips and allows patients to take preventive measures against osteoporosis before they experience a broken bone. The procedure is non-invasive and painless, requires no preparatory drinks, medications, or injections, and can be conducted in just minutes.

Physicians will use the test to measure a patient’s bone mineral density (BMD), and then compare the density to a test population

of similar age, gender, and ethnicity. Changes in bone density over time can also be measured.
