DEXA – BONE DENSITOMETRY
To accurately detect osteoporosis, doctors commonly use DEXA bone densitometry to measure bone mineral density (BMD). DEXA is a low dose, quick, and painless procedure for measuring bone loss. Measurement of the lower spine and hips are most often done.
What are some common uses of this procedure?
- Patients with a personal or maternal history of hip fracture or smoking
- Men and women who have hyperthyroidism
- Men and women who have taken medications that are known to cause bone loss for an extended period of time
How should I prepare for this procedure?
Refrain from taking calcium supplements and any Osteoporosis medication for 48 hours before your procedure.
Wear comfortable clothing and avoid garments that have zippers, belts or buttons made of metal and under wire bras.
Let the technologist know if you’ve recently, within the last week, had any procedures that use barium or have been injected with a contrast material for another exam.
What can I expect during this exam?
The test takes between 10 and 30 minutes. You may be asked to undress and put on a gown. You’ll lie on a padded table and the x-ray tube will move above you. It is important that you remain as still as possible during the procedure to ensure a clear and useful image. During an examination of the hips, the technologist will place your foot in a brace that rotates the hip inward.
What will I experience during this exam?
DEXA is a simple, painless and non-invasive procedure. Once on the examination table, you will be asked to remain still and to hold a position for a short period of time while the machine takes measurements.
