Bone densitometry is a low dose x-ray that checks for signs of mineral
loss and bone thinning. The areas x-rayed are usually your hip, spine
and/or wrist. The most accurate results are given when your test is done
on the spine or the hip. These are the most common areas of fracture if
you have osteoporosis.
Preparation
Wear clothing without zippers or metal buttons. Do not take any calcium
supplements the day of your exam.
Important things to tell your technologist:
Any personal history of fractures in your hips or lower back
Any personal history of surgeries in your hips or lower back where metal
was placed
When and where your last bone density test was performed
If you have a diagnosis of osteopenia or osteoporosis
If you are pregnant
Note: The imaging staff is trained to acquire images for a radiologist to review.
The radiologist is specially trained to look at x-ray studies and make
a diagnosis off of them. The imaging staff is not fully trained to do
so, therefore we will not be able to give you results at the time of your exam.
Osteoporosis
The most common type of bone disease
Occurs when your body fails to form enough new bone.
Characterized by progressive loss of bone density or strength, resulting
in an increased chance for fractures.
Most commonly associated with menopause
Insufficient calcium intake
To help prevent it:
Diet—adequate amount of calcium, vitamin D, and protein. May even
need a supplement of calcium.
High calcium foods—low fat milk, yogurt, cheese, salmon, green leafy
vegetables
Exercise—weight-bearing, like walking
Stop unhealthy habits—if you smoke, quit. Limit alcohol and caffeine intake
Prevent falls—to prevent fractures
Medications—some are used to slow the rate of bone loss
