Bone Densitometry, or DEXA, is a radiology procedure which determines bone mineral density or bone mass. Below-normal bone density can indicate problems such as osteoporosis – a condition that involves gradual loss of calcium, causing bones to thin, become fragile, and more likely to break. Osteoporosis is most common in women after menopause but it can also affect men and younger women. DEXA is painless and takes approximately 15 minutes. You will be asked to lie on your back on a table and the scanner will pass over your body to take pictures.
Preparing for a DEXA Exam
- You cannot take any non-chewable calcium supplements for 2 days prior to your appointment.
- Wear comfortable clothing the day of the exam. You will be asked to change if you are wearing any metal such as snaps and zippers as they interfere with the test.
