Bone densitometry, also called dual-energy x-ray absorption (DEXA), uses a very small dose of radiation to produce an image, usually of the lower spine and hips, to measure bone loss.
Your doctor may order a DEXA scan to:
During a DEXA
You may be asked to lie on your back on a padded table. The technologist will position your body to obtain the necessary images. A movable arm will pass over your body while you remain still. An exam typically takes 15-30 minutes.
After a DEXA
After a DEXA, you generally can resume normal activities with no side effects.
The DEXA scanner calculates a numerical reading of bone strength, called a T-score, which is used to compare your bone density with established values. Your doctor will receive a results within 24 hours and will then discuss with you what further procedures, if any, are needed.
