Dual energy x-ray absorptiometry (DEXA) is an enhanced form of x-ray technology that is used to measure bone loss. A DEXA scan provides a baseline for bone density and is a useful guide for physicians to monitor osteopenia and osteoporosis in patients.
Preparing for a DEXA scan:
Do not take any calcium supplements the day before or the day of the exam.
Do not take any calcium or iron supplements the day before or the day of your exam (excluding bone repair medications like Fosamax, Avista or Boniva).
Avoid scheduling any exam that requires contrast during the seven days prior to your DEXA scan. This includes barium, nuclear medicine studies, or IV contrast studies.
Wear comfortable clothing with no metal around the waist or spine (e.g., zippers, buttons, snaps).
