The unit of these histoPET values was called 'relSUV' (in analogy to SUV in PET), which may be interpreted as smoothed tumor likelihood.
It is tempting to speculate that this underlies the observed, reversible hypometabolism on FDG-PET, which may be due to a persistent NMDAR hypofunctional state after the initial acute inflammatory and hypermetabolic phase observed by others.
Its limitations are due to potentially increased glucose uptake in benign inflammatory lymphadenopathy and the limited spatial resolution of PET which may prevent differentiation between the primary tumour and adjacent lymph node metastases.
In this study, 86% of patients were staged with PET-CT, which may explain why 2-year survival rates (56%) were higher than anticipated (35%).
In particular, including FDG and amyloid PET biomarkers, which may help separate mild cognitive impairment subtypes (Prestia et al., 2013), and in due course tau-PET will be of considerable interest.
As the U-SPECT-II can be adapted to perform collimated imaging of PET tracers (VECTor, [35],[36]), this might even enable combined Cerenkov and PET imaging studies, which may help in the interpretation of Cerenkov findings.
This will result in anatomical mismatches between PET and CT, which may cause incorrect AC [11,12].
We have developed an optimized triple fusion reporter construct DsRedm-fl-ttksr39 for more effective and sensitive in vivo animal imaging using fluorescence, bioluminescence, and PET imaging modalities, which may facilitate different fields of biomedical research and applications.
The DsRedm-fl-ttksr39 triple reporter gene is less cytotoxic, more effective, and sensitive for in vitro cell imaging as well as in vivo animal imaging using fluorescence, bioluminescence, and PET imaging modalities, which may facilitate different fields of translational biomedical research and applications.
We also aim to provide insights into the PET process in general which may be helpful for the design of dyes and materials applying PET for other purposes.
