Overview of DEXA
DEXA is a scan measuring bone strength, commonly referred to as bone density. We lose bone density as we age, which can raise our risk for osteoporosis and bone fractures. Osteoporosis is the term used to describe brittle bones and the increased risk of having broken bones. Bone fracture is the term for a bone break. DEXA measures the mineral content of bones in particular areas of the body, and it provides information to doctors about your risk for the aforementioned bone conditions.
Who should receive a DEXA scan?
Healthcare providers often recommend a DEXA scan for people older than 50, who have had a broken bone or have other illnesses that put their bone health at a higher risk. However, doctors consider many factors when determining who might benefit from a DEXA scan; family history, medications, and overall health all impact a person’s risk for bone illnesses. Women usually begin losing bone mass earlier than men, so it is common for women to receive scans at younger ages than men.
What is a DEXA scan like?
DEXA bone density tests are done on an outpatient basis. You will likely continue your normal routine before the test unless your doctor directs you otherwise. Receiving a DEXA test is very similar to having a standard X-ray scan. A DEXA scan takes around 15 minutes. You will be asked to lie on a table. The arm of the scanner will scan your spine and hips, creating images of your bones. The doctor will be able to evaluate the mineral content of your bones from the images.
Are there any risks associated with DEXA?
There is a very small amount of radiation used in DEXA scans, similar to the amount of radiation used in standard X-ray scans. Added exposure to radiation can slightly increase the risk of developing cancer later in life. You should not have a DEXA scan if you are pregnant. Often, the benefits of a DEXA scan outweigh the low risks of radiation exposure, and DEXA is considered a safe test for most people.
