Imaging and analysis of thin structures using positron emission tomography: Thin phantoms and in vivo tobacco leaves study

In this work, a novel approach utilizing the designed phantoms imitating the plant tissues was applied for the evaluation of the relationships between the parameters of the prepared phantoms and/or quantitative variables obtained within the PET analysis. The microPET system developed for animal obje...

Description
Summary:In this work, a novel approach utilizing the designed phantoms imitating the plant tissues was applied for the evaluation of the relationships between the parameters of the prepared phantoms and/or quantitative variables obtained within the PET analysis. The microPET system developed for animal objects and approaches used made it possible to obtain the quantitative data in the form of 18F radioactivity as well as the glucose (in µg) accumulated in leaf tissues within the dynamic in vivo study. •A new approach utilizing designed phantoms imitating plant tissues was applied.•Relationships between phantom parameters and/or variables obtained by PET were found.•Imaging in vivo dynamics of 2-[18F]FDG transport in leaf tissues was carried out.•Quantitative data of 18F radioactivity and glucose in leaf tissues were obtained.•Processes responsible for 2-[18F]FDG transport within the leaf blade were discussed.
