Mechanism of action

11C-choline is a radiolabeled tracer where carbon-11 is incorporated into choline, a precursor for phosphatidylcholine synthesis. Rapidly dividing and metabolically active cells, including cancer cells, exhibit increased choline uptake and incorporation into cell membranes. The radioactive carbon-11 allows detection via PET imaging, facilitating localization and characterization of tumors.
