DEXA Bone Density Measurement
Bone density measurement using dual energy X-ray absorptiometry (DEXA) is the safest, most reliable and most cost effective way to diagnose and quantitate osteoporosis and to monitor treatment.
Answers to Commonly Asked Questions
Q. What is bone density measurement?
A. A bone density measurement will determine your bone mineral density (BMD) for the area measured and compare that result with the average BMD of young adult normals of your sex and race at their peak BMD. This information will help your doctor determine if you need to take certain steps to protect your bone health. Bone density measurement is simple, safe, noninvasive and painless - and you don't need to undress.
Q. How long does a measurement take?
A. A measurement usually takes from 5 to 20 minutes. You will be asked to be very still during this time.
Q. How much radiation will I be exposed to?
A. You will be exposed to very little radiation - in fact, in most cases, less than 1/20 the exposure of a standard chest X-ray. As with any medical procedure, be sure to tell your doctor if you are pregnant.
Q. What should I wear?
A. Wear comfortable clothing, preferably something without metal buttons, buckles or zippers.
Q. Is a bone density measurement the same as a bone scan?
A. A bone scan, which may help in identifying certain bone abnormalities such as infection, inflammation and cancer, requires an injection of radioactive material. A bone density measurement requires no special preparation, medication or injection.
