What is a DXA (Bone Density) procedure like?

Bone densitometry, using an advanced technology called DXA involves lying on a padded surface.  It safely and and accurately measures the bone mineral density in the hip and spine.  For the hip scan, legs are extended with the feet held in a positioning block.  For the lower spine span, legs are elevated on a cushion.  Each scan takes five to ten minutes.  There is no discomfort, and there are no injections or special dyes.  Unlike other x-ray machines the radiation exposure is extremely low.

Who Should Have a DXA Scan?

•  Women approaching or past menopause
• If you are thin or small framed
• If you have a family history of Osteoporosis
• If you take steroids or thyroid medication
• If you smoke or drink alcohol in excess
• If you have a sedentary lifestyle and do not do weight-bearing exercises

What patients should know before the test?

• There is no need to disrobe if you wear clothes without buttons, zippers or plastic closures.  We suggest a warm-up suit or shorts or pants with an elastic waistband.
• You should not have the exam within one week after any kind of barium x-ray or bone scan studies.
• Do not take any calcium or vitamin supplements the day of the exam.
