DXA Bone Density Study

What is Osteoporosis?

Osteoporosis is a thinning and weakening of the bones that happens as we age. Approximately 54 million Americans have osteoporosis and low bone mass, placing them at increased risk for osteoporosis. Studies suggest that approximately one in two women and up to one in four men age 50 and older will break a bone due to osteoporosis.

Osteoporosis is often called a silent disease because you can't feel bones weakening. Breaking a bone is often the first sign of.

What is a DXA?

Bone Densitometry or DXA (Dual X-ray Absorptiometry) is a quick, accurate and non-invasive way of detecting osteoporosis and bone loss which increases the risk of hip and spine fractures. A DXA scan is currently the most widely used test in measuring bone mineral density. It is an important test in assessing the degree of bone thinning in osteoporosis.

A DXA scan is highly recommended for women over age 65, as well as for women that are post-menopausal, have had complete hysterectomies or those individuals who have suffered certain types or frequent bone fractures.

Other risk factors that may warrant this scan are:

Osteoporosis can also seriously impact men. Low estrogen puts men at risk for broken bones. Osteoporosis particularly affects prostate cancer patients whose estrogen production is suppressed.

Preparing for DXA

On the day of your DXA study, you may eat normally; however, you should not take any calcium supplements for at least 24 hours before your exam. You may be asked to remove any jewelry, eye glasses or other metal objects on your clothing because they may interfere with the x-ray images. It is best to come to our imaging center dressed in loose, comfortable clothes. Be sure to inform the technologist if there is any chance you may be pregnant or if you have recently had any other imaging exam where you were given a contrast material such as oral barium, an IV or if you've recently received a scan using a radioisotope.

During and After DXA

During a DXA scan, you will lie flat on a padded table. A camera will be moved above you and focused x-ray images will be taken of the hip and lower spine where fractures are most likely to occur. You will not see or feel anything during the exam. The procedure takes approximately 15-30 minutes.

After the exam, you can return to normal activity. One of Arcadia Radiology Medical Group's Radiologists will interpret the exam and report the findings to the patient's physician.

What Does the Scoring on the Report Mean?

The patient's potential risk for Osteoporosis is expressed in two measurements or scores. The first is a T-score that compares your bone mass with that of a healthy young adult. Any score above -1 is considered normal. A score between -1 and -2.5 indicates low bone mass or osteopenia, the precursor to osteoporosis. A score below -2.5 is defined as osteoporosis.

The second measurement is a Z-score. This number compares your bone mass with other people in your age group. If this score is unusually high or low, your physician may recommend additional medical tests.
