Measurements of your bone density are made using a dual energy
x-ray beam. These measurements are compared with a reference population
to diagnose such conditions as osteopenia and osteoporosis.
Bone Densitometry Machine
A Fast Simple Examination
Your bone densitometry examination may be the easiest medical examination
you will have over the course of your life. Basically, all it involves
is for you to lie back and let the bone densitometer do the work.
However, there are always valid concerns about any medical procedure.
For your peace of mind, here are the answers to some questions you
may have.
What Will the Examination Determine?
The bone densitometer will measure your bone mineral density (BMD).
It will also compare your measurements to a reference population
based on your age, and sex. Your physician will use this information
in making a diagnosis about your bone status and fracture risk.
Will It Hurt?
Absolutely not. There is no pain at all associated with the bone
densitometry examination.
How Long Will The Examination Take?
Spine (lower back) or femur (hip) measurements may take approximately
ten to fifteen minutes each.
What Do I Do During The Examination?
Lie still. Breathe normally. Rest comfortably.
Is The Examination Safe?
Bone densitometry involves a small dose of radiation. How small?
A spine scan delivers less than one-tenth the dose of a chest x-ray.
As in any medical procedure, if there is a chance that you might
be pregnant, please be sure to inform your doctor.
Is There Any Special Preparation Involved?
Unlike many other medical examinations, no special preparation
is required. There are no painful contrast injections, bad tasting
oral preparations, or uncomfortable enemas.
If you have a diagnostic test that requires x-ray contrast material
(such as a CT scan or angiogram) within seven days prior to your
appointment, let us know as this may interfere with the results.
What Should I Wear?
Wear loose and comfortable clothing. Sweat suits and/or elastic-
waisted clothes are preferred. If possible, do not wear tops with
buttons or pants with zippers, buttons, or grommets. You will be
required to remove your bra because of the hooks.
Do I Have To Alter My Eating Habits?
This is not an examination that requires you to have an empty stomach,
drink a certain amount of water, or any other such pre-examination
preparation on your part. Follow your normal diet and medication
routine.
