iDEXA scanning appears safe for nearly anyone. There are situations in which it may be inaccurate:
- People having radioactive iodine thyroid treatment
- People who have had a nuclear medicine study or a barium X-ray within the last 5 days
- People with large amounts of metal in their bodies
- People with significant arthritis of the spine
An iDEXA scan is permitted once every 92 day period. iDEXA is not recommended for pregnant women.
