Indium Scan

An Indium scan is a type of nuclear medicine imaging test that uses a radioactive substance known as indium-111 to create detailed images of certain internal organs and structures within the body. This scan is particularly useful in detecting certain types of cancer, infection, and inflammation.

Procedure

The procedure for an indium scan involves the injection of a small amount of indium-111 into the patient's bloodstream. This radioactive substance travels through the blood and accumulates in certain tissues and organs. A special camera, known as a gamma camera, is then used to detect the radiation emitted by the indium-111 and create images of the inside of the body.

Uses

Indium scans are often used to detect and monitor certain types of cancer, including lymphoma and leukemia. They can also be used to detect infections and inflammation in the body, particularly in patients who have had recent surgery or who have immune system disorders. In addition, indium scans can be used to evaluate the function of certain organs, such as the lungs, heart, and kidneys.

Risks and Side Effects

As with any medical procedure, there are potential risks and side effects associated with indium scans. These may include allergic reactions to the indium-111, radiation exposure, and temporary discomfort at the injection site. However, the amount of radiation used in an indium scan is generally low, and the benefits of the procedure often outweigh the potential risks.
