Does a bone scan involve radiation?
There is a certain amount of radiation involved in a bone scan.
A bone imaging agent must be injected into the body during a bone scan. This agent contains a small amount of radiation and is a radioactive isotope. After injection, the imaging agent helps visualize the bones during the scan, aiding in detecting any bone-related abnormalities. Although a bone scan does involve some radiation, the dose is low and within a range considered safe for humans. It generally does not affect health, as long as the scans are not performed too frequently. There is usually no need for excessive concern if the procedure is done only occasionally.
Bone scanning is one of the commonly used diagnostic procedures in nuclear medicine. A whole-body isotope bone scan detects structural or metabolic abnormalities in bone tissue using radioactive isotopes. Before the scan, a radioactive tracer is injected, and after waiting 2 to 3 hours for adequate uptake by the bones, a specialized imaging device is used to detect the distribution of radioactivity throughout the entire skeleton, thereby helping to clarify the patient's condition.
