DEXA scan measures your bone density with a low dose of radiation, which is interpreted by sophisticated computer analysis. Your test results will assist your physician in determining whether you need treatment for bone loss.

What to expect during your bone densitometry exam

A bone densitometry exam is simple and painless. You’ll lie down on a padded table, relax, be as still as possible and breathe normally while a mechanical arm passes above your hip and spine. The entire procedure takes about 20 minutes.

How to Prepare for the procedure

Wear a comfortable two-piece outfit without metal zippers, snaps or under-wire bras. Bone densitometry should be scheduled at least a week after any procedure involving barium (upper GI series, small bowel series or barium enema).
