Bone Marrow Scan for Bone Infection
It is important to detect a bone infection--also known as osteomyelitis--early because it can spread to other parts of the body, such as muscles and tendons. A bone scan is a test that is used to find out if people have bone problems, such as a bone infection.-
Definition
-
A bone scan measures bone metabolism, or the natural processes involved in bone growth. Bone abnormalities can signal that a person has an infection or another bone problem, such as a fracture.
Procedure
-
During a bone scan, a doctor injects a radiotracer into your vein and then uses a gamma camera to produce images of areas where the radioactive substance has collected, according to CancerHelp UK. Usually a doctor will also perform one or more bone scans on you after the radiotracer has collected in your bone tissue, three to four hours after you are first injected, according to Lancaster General Health.
Results
-
The radiotracer will gather in areas where bones are experiencing abnormal growth, which can be indicative of a bone infection, according to MedlinePlus. Further tests, such as a computed tomography or magnetic resonance imaging scan, are often needed to show the cause of bone irregularities, according to the Mayo Clinic.
Preparation
-
Before getting a bone scan, take off all metal objects that are you wearing, including jewelry. While you are waiting for the tracer to collect in your bone tissue, drink water to rid your body of excess radiotracer, according to Lancaster General Health.
Risks
-
Women who are pregnant or nursing should not undergo a bone scan, because the radioactive substance that is used during the procedure is harmful to babies.
