Bone Density Study - DEXA

What is DEXA?

Dual-Energy X-ray Absorptiometry (DEXA) examinations estimate the amount of bone mineral content and in some cases bone loss in specific areas of your body. The scan measures the amount of x-rays that are absorbed into the hip and lower spine. These areas are the most common for loss of bone density and risk for fracture. The measurements are compared to national standards for normal bone density and suggest your present state of bone density and risk of fracture.

What should I expect?

You will be asked to lie very still on the scan table and you will be able to breathe normally throughout the procedure. A scanner arm will pass over the area to be measured. A dual energy beam of x-ray passes through your body and is measured by a detector in the scanner arm. An exam usually consists of a spine and a single scan of the hip. The exam will take about twenty minutes.

How should I prepare?

Unless instructed otherwise, eat normally on the day of the exam. If possible wear clothing that doesn’t have zippers or metal.

How do I get the results?

After your study is over, the test will be evaluated by one of the TRG radiologists with expertise in bone density. A final report will be sent to your doctor who can then discuss the results with you in detail.
