Who can use it? of DEXA scan

This scan is a safe procedure but because DEXA scanners are relatively costly, they are not freely available throughout the country, so high-risk groups are prioritised for scans.

The groups most likely to require a DEXA scan include:

  • Women of menopausal age who smoke or drink heavily, have a history in their family of hip fractures, or a body mass index (BMI) of less than 21;
  • Those who take oral steroids or corticosteroids for a long period (these medicines can contribute to weakening bones);
  • Older women who have had bad fractures;
  • Women who have early menopause or ovaries removed, under the age of 45;
  • Men with very high consumption of alcohol.

Pregnant women are advised against bone density testing. The scan may damage the unborn child, in the same way to ordinary X-rays.
