DEXA (Bone Densitometry)

Introduction

DEXA (dual energy x-ray absorptiometry) is used to measure bone mineral density (BMD). The technique uses very low dose x-rays and is a safe and painless procedure. The entire procedure lasts approximately 20 minutes. Low bone density or osteoporosis is a major determinant of fracture risk and is common, particularly in women following menopause. Loss of bone density may also be accelerated in conditions affecting the liver and thyroid gland and by certain medications, in particular, steroids. Measurement of the spine and hip is routinely performed and measurement of the forearm may also be undertaken if required.

  2. Follow-up of low bone density or fractures with minimal trauma, follow-up of bone density on therapy*
  3. Prolonged therapy with steroids, early menopause, male hypogonadism*
  4. Measurement of bone density may be indicated in chronic diseases including chronic liver and kidney disease*
