TL;DR: It is shown that it is possible to separate Cu-64 from Ni-64 and other reaction byproducts rapidly and efficiently by using ion exchange chromatography.

TL;DR: Results indicate the complexity and large variation of glucose uptake mechanism in tumors and that consistent performed procedures and more basic studies are needed to improve the utility of FDG SUV.

TL;DR: In this paper, the authors apply graphical analysis to both reversible and irreversibly binding tracers in order to provide insight into the binding kinetics of tracer kinetics in a visual way, and some problems encountered in separating tracer delivery and binding are considered.

TL;DR: This study attempted to replicate the original findings in an independent sample of subjects selected according to the criteria for primary recurrent depression applied in a prior study, and showed reduced 5-HT1AR binding potential in the mesiotemporal cortex (MTC) and raphe in depressives with primary recurrent familial mood disorders.

TL;DR: Small-animal positron emission tomography (PET) imaging studies have demonstrated that free (89)Zr(IV) ions administered as [(89) zirconium-89]Zr-chloride accumulate in the liver, whilst [(89’s) Zr-DFO is excreted rapidly via the kidneys within <20 min, which has important implication for the analysis of immuno-PET imaging of (89), as well as other radiochemistry facilities.
