Carbon-11 Choline PET-CT Scan

**Semantic type:** Diagnostic Procedure

**Definition:** A procedure in which a small amount of carbon-11 choline (a radioactive form of the vitamin choline) is injected into a vein. A scanner and a computer are used to make detailed pictures of areas inside the body where the carbon-11 choline collects. Cancer cells take up more carbon-11 choline than normal cells, so the pictures can be used to find cancer cells in the body.
