11C-labelled radiotracers such as [11C] raclopride are produced in a process that can take between 45 and 60 min to complete. These conventional approaches can consume upwards of 75% of the 11C (t 1/2= 20 min) due to radioactive decay alone, even more if synthesis losses are considered. To compensate, a large starting quantity of radioactive precursors such as [11C] methyl iodide is required to produce an adequate amount of the ...
