F-18 FDG was synthesized using the GE FASTlab FDG Citrate cassette. The F-18 FDG product has the same quality control specifications, whether it was done via MGH's traditional method or Tracer-QC method as detailed in Table 1. A minor difference is that the Rf of F-18 FDG sample for...
In autonomy patients F-18-FDG uptake increased with increasing radioiodine uptake and shorter radioiodine half-life. These results indicate that glucose metabolism is enhanced in the thyroids of patients with focal and disseminated autonomy. The negative correlation of radioiodine half-life and glucose ...
The first of them was 11C-methionine (MET); however, its use is limited because carbon 11’s half-life is 20 min and it is reserved for PET centers with an on-site cyclotron unit. Other amino-acid radiotracers labeled with fluor 18 have been synthetized, such as [18F]-fluoroethyl-...
Fluorine-18 is one of the several isotopes of fluorine that is routinely used in radiolabeling of biomolecules for PET; because of its positron emitting property and favorable half-life of 109.8 min. The biologically active molecule most commonly used for PET is 2-deoxy-2-(18)F-fluoro-β-D...
11C-labeled Pittsburgh compound B (PiB) was the first PET tracer to image cortical Aβ plaques8,9, and prior PiB studies have shown that PiB-positive normal and MCI subjects are more likely to show faster cognitive deterioration than PiB-negative subjects.10–19 The short half-life of 11C ...
