Define a Bone Scan

A bone scan is a test that is done to identify bone breakdown or areas of new bone growth. Bone scans are also useful in finding bone cancer in an individual and also determining whether or not the cancer had spread to the bones from another area. A bone scan may be done on a small area of the body or on its entirety.

Why is it Done?

A bone scan is done in order to diagnose the location and cause of any unexplainable bone pain. It can also help to locate any damage done to the bones by infections or other medical conditions.

How do you Prepare for a Bone Scan?

Before the test is performed, the individual should inform the physician if they have taken any medications that contain bismuth. The chemical element, bismuth, can interfere with the results. The individual will also be asked to limit their fluids for up to four hours before the test.

How is a Bone Scan Done?

A small quantity of radioactive tracer is injected into the individual's arm. It takes roughly two to four hours for the tracer to attach to the bone. The individual will be asked to lie on their back while a large camera scans their body. The bone scan, itself, will take about an hour to complete.

How Does it Feel?

A bone scan is usually painless besides the fact that the individual may feel a pinch from the puncture of the injection needle. It may be uncomfortable for some to remain still while the scan is being performed.

Are There Any Side Effects?

Some individuals may notice some swelling or soreness around the injection site. The risk of having damage done to the cells or tissue is slight. Allergic reactions to the bone scan tests are rare. Most of the tracer will be gone from the body within a day.
