The most stable artificial radioisotope is 11 C, which has a half-life of 20.3402(53) min. All other radioisotopes have half-lives under 20 seconds, most less than 200 milliseconds. The least stable isotope is 8 C, with a half-life of 3.5(1.4) × 10 −21 s. Light isotopes tend to decay into isotopes of boron and heavy ones tend to decay into ...
3 kwi 2019 · This can easily be understood by considering that the ratio between the total mass of a 11 C-labeled precursor (carbon-12 and carbon-11) and the precursor for labeling typically is in the order of 1/100.
In this review paper, we first briefly introduce some basic principles of PET imaging of cancer; we then discuss principles of carbon-11 radiochemistry, focus on specific advances in radiochemistry, and describe the synthesis of C-11 radiopharmaceuticals developed for cancer imaging.
Show only decays with probability >0.1%. Click any isotope in diagram to see its data. Detailed decay information for the isotope carbon-11 including decay chains and daughter products.
1 kwi 2010 · The optimization of conditions for making a carbon-11 tracer include the late introduction of the C-11 isotope, the rapid formation and purification of the target compound, and the use of...
8 kwi 2020 · To support the PET imaging study of the metabolic process of ketone bodies in brain tumors, we recently developed a production method for [11 C]acetoacetic acid ([11C]3) following a...
