What is DEXA?

DEXA (Dual Energy X-ray Absorptiometry), or bone densitometry is an imaging examination that can diagnose osteoporosis by precisely measuring the bone density and the mineral content of bone. Osteoporosis has been called the "silent disease" because it doesn't produce symptoms, until a fracture occurs. One out of two women over the age of 50 are at risk for an osteoporotic fracture. A DEXA scan can detect bone loss even in its earliest stages. Once bone loss is detected, your physician can effectively treat it. Utilizing very low levels of x-rays, the DEXA scan measures the bone density of fracture-prone areas like the hip and spine.

Who is at risk for Osteoporosis?

Your chances of developing osteoporosis are higher if you are female and have one or more of the following risk factors:

	Caucasian decent
	Thin or small body frame
	Approaching or past menopause
	Low calcium intake
	Cigarette smoker
	Excess intake of alcohol
	Sedentary lifestyle
	Family history of osteoporosis

Your DEXA Experience

A DEXA exam is simple and painless. You will be asked to lie still on the examination table while the scanner measures the density of your hip and spine. If you wear clothing without any zippers or buttons, it is not necessary to even undress for the scan. The entire process takes about 15 minutes to complete. Once your exam is finished the radiologist will analyze your bone density and compare your bone to normal bone density values. These results will then be sent to your doctor. If necessary, your doctor can determine if any lifestyle changes or treatment measures should be taken.
