DEXA Scan
Loss of bone density is part of aging and can lead to problems with osteoporosis. A physician-ordered Dual-Energy X-ray Absorption, or DEXA, scan will help assess the risk of fractures related to osteoporosis.
Osteoporosis risk factors include:
- Female
- Caucasian
- Advanced age
- History of bone fractures
- Small, thin frame
- Family history of osteoporosis
- Removal of ovaries
- Early menopause
- Low-calcium diet
- Lack of exercise
- Eating disorders
- Certain medications
- Alcohol and tobacco use
What is a DEXA Scan?
A DEXA scan uses X-ray to measure the amount of bone material or density, which is directly related to bone strength. Measurements are taken from the spine and hip, where fractures caused by osteoporosis occur most often. The information is sent to a computer and used to help determine the diagnosis.
Preparing for the Exam
DEXA testing is a quick, safe test that takes about 10 minutes. Patients remain fully clothed but may be asked to remove belt buckles and metal jewelry.
NOTE: Do not take calcium supplements the day of the DEXA scan.
