This characteristic of FC is similar to other standard scan types, such as structural or diffusion MRI. But importantly, FC allows examination of functional neural architecture, or brain activity fluctuations over time. Further, FC uniquely potentiates investigation of early, brain-based biomarkers of...
produced exosomes-mimetic nanovesicles (ENVs) from extrusion of macrophage cells and radiolabeled them with 99mTc-hexamethylpropyleneamineo (HMPAO) under physiologic conditions [21]. The conversion of 99mTc-HMPAO in the hydrophilic form that is confined inside cells is accom- plished by intracellular...
Therefore, it might be more appropriate to assess tumor response by metabolic activity, which can be measured by FDG uptake on PET or [18 F] FDG PET/CT. Decrease in FDG uptake after treatment may prove to be a better indicator of a favorable response rather than change in tumor size (...
Overall, we can state that in AE cortical involvement with restricted diffusion on DWI is uncommon unless related to cytotoxic edema associated with epileptic activity. Outside this instance, cortical involvement with restricted diffusion should lead to consider other pathological entities in the ...
[179,180,181]. Additionally, cognitively normal adults who self-report sleep issues are more likely to have amyloid pathology in their brains on PET scan [182]. Aβ levels have been shown to be regulated by the sleep–wake cycle. When brain interstitial fluid (ISF) is sampled in mice ...
