What is a bone density scan?
A bone density scan (DXA) is an enhanced form of X-ray technology that is used to measure bone loss. It is used to diagnose osteoporosis, a condition that causes bones to decrease in density over time. The scan provides a true test for the effects of osteoporosis as well as other conditions that cause bone loss. It can also assess a patient’s risk for developing fractures. Depending on the part of the body being studied, the procedure usually takes between 10 to 20 minutes and is painless.
