One side field of PET system or PET imaging assessment is that of lesion detection.
In the field of PET imaging, a variation of the basic Otsu method has been introduced as a solution to the PET segmentation problem [13].
As recently pointed out by Hofman and Hicks [6], pattern recognition appears to be of great value in the field of PET imaging.
In the field of PET system development, there is a continuous effort in improving the performance of the next generation system.
Consequently, earliest attempts to access this group by nucleophilic and electrophilic radiofluorination protocols date back into the very beginnings of the field of PET chemistry (see Table 1 for an overview).
At the time when the highly efficient [F]FDG synthesis was discovered by the use of the effective precursor 1,3,4,6-tetra 1,3,4,6-tetra -trifluoromethanesulfO-acetyl-2mannopyranose (mannose triflate) for nucleophilic F-substitution, the field of PET in nuclear medicine experienced a long-term boom.
Since their introduction in 2000 their potential to be used in pretargeting experiments has drawn much attention in the field of (PET-) imaging.
For the heterogeneous lesion (Figure 5A), the SUVmax is decreased by 18%, MTV is increased by 39%, and TLG by 20% (all for CT5 and RF) which might be a notable impact, for example, on the repeated measurement in follow-up studies due to error propagation or in the field of PET-based planning of radiotherapy [30, 31] where an accurate MTV definition is important.
Compared with malignant lymphoma, less data are available in the field of PET-controlled trials in solid tumors (Table 4).
The development of new PET tracers that possess imaging, targeting, and therapeutic functions will remain key elements of future research in the field of cardiac PET, which will be a useful tool to monitoring new therapeutic strategies in the battle against cardiovascular disease.
