Bone Densitometry is used to measure bone mineral content and density.

A bone density test is also called Bone Densitometry determines if you have osteoporosis — a disorder characterized by bones that are more fragile and more likely to break. Shreya Hospital at Ghaziabad has the best Bone Density Test facility available in the hospital premises. Center is having expert technicians to undergo the testing procedure.

The test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. The bones that are most commonly tested are in the spine, hip and sometimes the forearm.

Doctors use Bone Densitometry to:

• Identify decreases in bone density before you break a bone
• Determine your risk of broken bones (fractures)
• Confirm a diagnosis of osteoporosis
• Monitor osteoporosis treatment

The higher your bone mineral content, the denser your bones are. And the denser your bones, the stronger they generally are and the less likely they are to break.

Bone Densitometry differ from bone scans. Bone scans require an injection beforehand and are usually used to detect fractures, cancer, infections and other abnormalities in the bone.

Although osteoporosis is more common in older women, men also can develop the condition. Regardless of your sex or age, your doctor may recommend a bone density test if you’ve:

• Lost height. People who have lost at least 1.5 inches (3.8 centimeters) in height may have compression fractures in their spines, for which osteoporosis is one of the main causes.
• Fractured a bone. Fragility fractures occur when a bone becomes so fragile that it breaks much more easily than expected. Fragility fractures can sometimes be caused by a strong cough or sneeze.
• Taken certain drugs. Long-term use of steroid medications, such as prednisone, interferes with the bone-rebuilding process — which can lead to osteoporosis.
• Had a drop in hormone levels. In addition to the natural drop in hormones that occurs after menopause, women’s estrogen may also drop during certain cancer treatments. Some treatments for prostate cancer reduce testosterone levels in men. Lowered sex hormone levels weaken bone.

Preparation for Bone Densitometry:

Bone density tests are easy, fast and painless. Virtually no preparation is needed.

Be sure to tell your doctor beforehand if you’ve recently had a barium exam or had contrast material injected for a CT scan or nuclear medicine test. Contrast materials might interfere with your bone density test.

Food and medications

Avoid taking calcium supplements for at least 24 hours before your bone density test.

Clothing and personal items

Wear loose, comfortable clothing and avoid wearing clothes with zippers, belts or buttons. Leave your jewelry at home and remove all metal objects from your pockets, such as keys, money clips or change. At some facilities, you may be asked to change into an examination gown.

Procedure:

If you have your bone density test done at a hospital, it’ll probably be done on a device where you lie on a padded platform while a mechanical arm passes over your body. The amount of radiation you’re exposed to is very low, much less than the amount emitted during a chest X-ray. The test usually takes about 10 to 30 minutes.

A small, portable machine can measure bone density in the bones at the far ends of your skeleton, such as those in your finger, wrist or heel. The instruments used for these tests are called peripheral devices and are often used at health fairs.

Because bone density can vary from one location in your body to another, a measurement taken at your heel usually isn’t as accurate a predictor of fracture risk as a measurement taken at your spine or hip. Consequently, if your test on a peripheral device is positive, your doctor might recommend a follow-up scan at your spine or hip to confirm your diagnosis.
