Bone Densitometry, also known as Dual energy X-ray Absorptiometry or DEXA, is a special type of X-ray used to measure the calcium content of the bone. The examination is also called a DEXA-scan, or BMD (bone mineral density) measurement. used to measure and monitor changes in bone density. The gradual loss of density weakens the bones and leads to fractures. This condition is called osteoporosis. Many factors such as dietary habits and family history contribute to the development of this disease. A bone densitometer can let patients know whether or not they have osteoporosis or if they are at risk of developing the disease.

Your doctor may have recommended you have a bone densitometry scan because:

• An x-ray reveals low bone mass (osteopenia) or
possibly osteoporosis

• You are 65 or older or have begun menopause

• You have a family history of osteoporosis

• You are taking or have taken steroids taken on a regular basis

• You have hyperthyroidism, diabetes,
liver/kidney disease or rheumatoid arthritis

Bone Density Scans require no preparation on your part. You will lie down on an exam table where two low-dose x-rays measure the bone density in your body. The Bone Densitometer accurately measures your bone mineral density and records the pictures onto a computer located nearby.

The bone density score determines if you have osteopenia (low bone mass) or osteoporosis. A woman’s bone mass peaks around age 35 and levels off during menopause. Bone density declines sharply during the first years of menopause. A Bone Densitometry Scan can detect as small as 1% loss in bone mass.

approximately 10-20 minutes

An experienced board certified radiologist at Central Georgia Diagnostics will read the tests and promptly send the report to your doctor.

As always, please let your doctor or the technologist know of any concerns or questions you may have prior to this exam. It is our goal to ensure you have an accurate and comfortable exam.
