Bone Mineral Density Scans
What is a Bone Mineral Density DEXA Scan?
The bone mineral density DEXA Scan is the gold standard test for diagnosising osteoporosis. It is done to determine if you have osteoporosis or are at risk of developing osteoporosis before breaking any bones.
How can I prepare for this test?
No special preparation is necessary. You will be asked to fill out a questionnaire with pertinent information for the test. The technologist will need to be informed if you've had any barium or IV contrast studies, or any Nuclear Medicine tests done recently (within the past week). These will interfere with this test. Wearing pants with no metal on them such as sweat pants, is helpful.
How is the test done?
Before you enter the room, your information along with the contents of the questionnaire will be entered into the BMD computer. We will ask you to empty the contents of your pants pockets and have you lie down on the padded table. An immobilizer will be placed between your feet and your feet will be secured with velcro straps. A mechanical arm-like device will pass over your hip area. The machine will not touch you. When finished your feet will be freed and the immobilizer will be removed. Next a square sponge will be placed under your knees. The arm-like device will then pass over your lower back area.
This test does use radiation; however it is low dosage, and uses about one-tenth the amount you receive from a chest x-ray.
How long will the test take?
The DEXA scan takes about 10 minutes. It is not a scheduled test, therefore, the test will be done on a first come first serve basis.
How are the results used?
The scan will be analyzed by the technologist. The computer will print a report with your results. Your physician will receive this report and interpret it. He will discuss it with you at your next appointment along with a course of treatment if necessary.
What else do I need to know?
Bone Mineral Densities are not the same as Bone Scans. BMD is a test to determine if you have or are at risk of having osteoporosis. A Bone Scan requires an injection prior to the scan and is used in detecting fractures, cancer, infections and abnormalities in bone.
Generally BMDs are repeated every two years, starting at approximately menopausal age. They are repeated yearly if on certain medications including steroids and bisphosphonates. Osteoporosis is a disease related to both men and women.
