What is a Bone Density Test (DEXA Scan)?
To detect osteoporosis accurately, doctors use an enhanced form of x-ray technology called Dual-energy x-ray absorptiometry (DEXA). Bone densitometry is today's established standard for measuring bone mineral density (BMD). DEXA is a quick, painless procedure for measuring bone loss. Measurement of the lower spine and hips are most often done.
What to Expect During the Exam
For a bone densitometry exam, you will lie on your back on the scanning table as scans are taken of your spine and hip. The scan is non-invasive and takes between 10-15 minutes. Medicare permits individuals to repeat BMD testing every two years.
Is the Bone Density exam safe?
In most cases, your radiation exposure will be a fraction of what you would receive from a standard chest x-ray. You may also be interested to know that the radiation exposure is actually about the same, as you would experience on a cross-country airline flight. As with any medical procedure, be sure to inform your physician if you are pregnant.
What is Osteoporosis?
Osteoporosis is a disease in which bones become fragile and more likely to break. If not prevented or if left untreated, osteoporosis can progress without symptoms or pain until a bone breaks. These broken bones, also known as fractures, occur typically in the hip, spine, and wrist. Up to 1.5 million fractures a year are attributable to osteoporosis. Osteoporosis is a complex disease and not all of its causes are known. However, when certain risk factors are present, your likelihood of developing osteoporosis is increased. Therefore, it is important for you to determine your risk of developing osteoporosis and take action to prevent it. The good news is that osteoporosis is preventable if bone loss is detected early and treated.
What are the risk factors for Osteoporosis?
- Family history
- Female
- Caucasian race
- Poor calcium intake
- Poor dietary vitamin D intake
- Low estrogen levels
- Small or thin body build
- Lack of activity
- Use of steroid for greater than 3 months
If you already have osteoporosis, you can live actively and comfortably by seeking proper medical care and making some adjustments to your lifestyle. Your health-care provider may prescribe a diet rich in calcium and vitamin D, a regular program of weight-bearing exercise and medical treatment.
