DEXA Bone Scan Houston TX

What is a DEXA Bone Scan?

A bone mineral density (BMD) test measures the mineral density - such as calcium - in your bones using a special X-ray, CT scan or ultrasound.

Why Is DEXA Performed?

A DEXA bone scan provides an estimate of the strength of your bones. DEXA uses two different X-ray beams to estimate bone density in your spine and hip.

The amounts of each X-ray beam that are blocked by bone and soft tissue are compared to each other. Bones with higher mineral density allow less of the X-ray beam to pass through them.

DEXA is the most accurate method for measuring BMD. DEXA can measure as little as 2 percent of bone loss per year. It is fast and uses very low doses of radiation but is more expensive than ultrasound testing.

How do I prepare?

Avoid wearing clothes with metal buttons or buckles for the test. You also may want to remove any jewelry that might interfere with the scan, such as a bracelet if you are having the scan done on your wrist.

How is a DEXA Bone Scan Done?

You will lie on your back on a padded table. You can usually remain fully clothed. You may lie with your legs straight or with your lower legs resting against a platform built into the table. The machine will scan your bones and measure the amount of radiation they absorb.

Testing at least two different bones each time - preferably the hip and spine - is the most reliable way of measuring BMD. It is best to test the same bones and to use the same measurement technique and BMD equipment each time.

How Does a DEXA Bone Scan Feel?

The DEXA technique, which scans the hip and lower spine, takes only about 20 minutes to perform. Usually there is no discomfort during a bone mineral density test. If you have back pain, it may be uncomfortable to lie still on a table during the scan.

What Happens After the Test?

A radiologist will interpret your exam. The technologist who administers the test cannot interpret or discuss what they are viewing while performing the exam. A report will be sent to your physician's office to discuss results.
