DEXA Scan

Bone densitometry (DEXA, DXA) is a simple, quick, non-invasive scan that helps identify a decrease in bone density and loss of bone strength.

It uses an extremely low dose of x-ray radiation to produce images of the lower spine and hips unlike a typical x-ray.

This measurement of your bone mineral density (BMD) can identify osteoporosis, osteopenia, determine your risk for bone fractures, and your response to osteoporosis treatment.

Candidates for Bone Density Exams

  1. Women age 65 and older, men age 70 and older
  2. Postmenopausal women under the age of 65 with one or more the following risk factors:
    • Family history of osteoporosis (mother or sister)
    • History of cigarette smoking, excessive alcohol or caffeine consumption
    • History of diabetes, hyperparathyroidism, or hyperthyroidism
    • Premature menopause or late onset of menstrual periods
    • Vitamin D deficiency
    • Long term use of medications known to cause bone loss (i.e., prednisone,
    • seizure medications, diuretics and Depo-Provera contraceptive injections).
    • Rheumatoid arthritis, Kidney, and thyroid conditions
    • Have had a broken bone after a minor fall or injury.

Diagnose Osteoporosis Early

Unlike plain film x-rays, DEXA can measure very small reductions in bone density. This makes it possible to diagnose osteoporosis in its early stage, before you break a bone.

Most severe osteoporosis is identified too late after spinal curvature (Kyphosis) or a non traumatic vertebral fracture.

Doctors use the results of bone density exams to help them decide whether treatment for low bone density is needed and then responses to osteoporosis treatment.
