DEXA
Dual-energy X-ray Absorptiometry, DXA, DEXA.
DEXA uses X-rays to measure the strength, density and mineral content of bone. DEXA is most often used
to diagnose osteoporosis, a condition that often affects women after menopause but may also be found
in men. Osteoporosis involves a gradual loss of calcium, as well as structural changes, causing the bones
to become thinner, more fragile and more likely to break.
DEXA is also effective in tracking the effects of treatment for osteoporosis and other conditions that
cause bone loss. DEXA can also access an individual's risk for developing fractures.

This bone density scan is a quick and painless procedure that involves lying on your back on an X-ray
table as your body will be scanned. A DEXA scan typically takes about 10 minutes.
On the day of your DEXA Scan at SMIL, you should wear comfortable, loose-fitting clothes. You will be
asked to remove any articles of clothing that may contain metal, such as belts, glasses, jewelry or
removable dental appliances that may interfere with the x-ray images.
You should inform your SMIL radiologist of any health conditions, illnesses or allergies before your exam.
Women should inform their SMIL radiologist if there is any chance they could be pregnant.
You should not take any calcium supplements for at least 24 hours before your exam.
Experiencing excessive radiation carries a slight risk of developing cancer. However, the benefit of an
accurate diagnosis far outweighs the risk. No radiation remains in a patient's body after a DEXA
examination.
Women should always inform their SMIL radiologist if there is any chance they could be pregnant.
