Transcript

Hello, my name is Dolores McCray. I'm a nuclear medicine technologist.

What is a tracer injection?

A tracer injection puts a small amount of radioactive material, called a tracer, into a vein. The tracer travels through the body and collects in certain organs or tissues. A special camera picks up the energy it gives off to make pictures.

A nuclear medicine technologist usually gives the injection. Depending on the test, scanning may start soon after or follow a wait. Over time, the tracer loses its radioactivity and leaves the body, often in urine.

Call the office if you have questions about your visit or your care. This is general information, not personal instructions. Your care team can tell you what applies to you.

Thanks for watching.
