Choline C-11 was the first PET tracer approved in the United States, in 2012, to find where prostate cancer has come back when PSA rises after treatment; PSMA tracers have now largely replaced it.
The FDA approved Choline C 11 Injection in September 2012, produced at the Mayo Clinic, for PET imaging of patients with suspected prostate cancer recurrence and non-informative bone scan, CT or MRI, the first approval of a PET agent for prostate cancer. Its 20-minute half-life means it must be made on site with a cyclotron, which confined it to a few centres. From 2020 the PSMA-targeted tracers gallium-68 PSMA-11 and piflufolastat F-18, with higher sensitivity at low PSA and longer half-lives, took over most recurrence imaging, and fluciclovine F-18 offered a distributable amino-acid alternative.
Carbon-11-labelled choline is taken up by cells with high phosphatidylcholine synthesis, including prostate cancer, and imaged by PET within minutes because of the isotope's 20-minute half-life.
