carbon-11 (11C)

a radioisotope of carbon with a half-life of 20 minutes. It is produced by a cyclotron and emits positrons. Compare carbon-14.

carbon-11

A positron-emiting radioisotope of carbon, which is produced in a cyclotron, has a T1/2 of 20.38 minutes, decays 100% by positron emission to 11B, and is used in PET scanning.

the scope of this equipment is the manufacture and preparation of suitable doses of radiotracer injection solutions containing either fluorine-18 or carbon-11 as radioisotope.
But new ways to remove carbon-11 from the analysis allowed the Borexino scientists to filter out the unwanted signal, Galbiati says.
Plus, all isotopes produced by the B14 including: Carbon-11, Nitrogen-13, Oxygen-15, Fluorine-18 (aqueous & gas), Copper-64, Iodine-124, Gallium-67, Technetium-99m and Palladium-103
In taking the next step, Maksimchuk and his colleagues fired laser-driven proton-neutron pairs, or deuterons, at a boron target to produce carbon-11.
They labeled methylphenidate with a radioactive tracer, carbon-11, and injected small doses into two volunteers.
Its energy is selected to be optimum for PET radioisotopes such as Fluorine-18 (for FDG), Nitrogen-13 (for Ammonia), and Carbon-11 (for Raclopride and other neuroreceptor agents).
The imaging of brain amyloid by carbon-11 PiB has been judged by Nature Medicine (Vol 12: 7, p767, 2006) to be one of the most significant advances in the field of AD in recent years.
Other compounds labeled with much shorter lived isotopes, such as Carbon-11 (20 min), Nitrogen-13 (10 min) or Oxygen-15 (2 min), require an on-site accelerator for their use in diagnostic PET scans.
