A DEXA scan is a special type of X-ray that measures bone mineral density (BMD). DEXA stands for "dual energy X-ray absorptiometry". This type of scan may also be called: a DXA scan or a bone density scan.

During the examination, you are required to change into light cloths and remove all jewelry. The technician guides you in taking the right position in front of the X-ray receiving plate. Depending upon the target body part, you may be asked to lie down or stand to facilitate the report.
