DEXA Bone Density Scan

Dual-energy X-ray absorptiometry, or DEXA, is the preferred technique for measuring bone mineral density. 

A patient must lie still on a table for a few minutes to complete a DEXA scan.

Patient Preparation Instructions
  • Please do not have a DEXA scan if you have had an oral contrast study in the last 48 hours.
  • Please do not take calcium supplements 24 - 48 hrs prior.
  • It is best to wear comfortable clothing, preferably no metal (zipper) at waist and no under-wire bra.


These are preparation guidelines for imaging exams performed at Knox Community Hospital (KCH). If you have any questions regarding prep for your exam, please contact us at 740.393.9038.
