      [18F]Fluorodeoxyglucose (FDG) uptake reflects glucose metabolism and has shown promise in discriminating symptomatic MCs from cognitively normal, mutation-negative non-carriers (NC) [6,9,10]. In ADAD, studies have shown FDG uptake in MCs is decreased in the precuneus and is inversely correlated with PiB binding.

      Nov 09, 2017 · 2) The evidence is not adequate to conclude that FDG-PET is reasonable and necessary for the diagnosis of patients with mild cognitive impairment (MCI) or early dementia in clinical circumstances other than that specified above absent safeguards that would be present in formal, protocol-driven clinical investigations.

      MSAC noted that the financial implications may be underestimated, but that uptake would be limited by the small number of FDG PET machines available. If currently 5% of Alzheimer’s disease diagnoses are inconclusive and so are referred for SPECT, then any MBS funding for FDG PET should be introduced in such a way as to not increase the ...

      FDG uptake into both tumors and other body tissues is a dynamic process that peaks and plateaus at various time points dependent upon multiple variables.25,26 Therefore, it is extremely important that (1) the time interval between FDG administration and the start of emission scan acquisition is consistent and (2) when repeating a scan on the ...

      However, FDG uptake is highly variable, possibly due to tumor cellularity, biological behavior of the tumor cells, composition of the inflammatory cell infiltrate, and the proportion and extent of activation of the inflammatory cells. Similarly, CT and magnetic resonance imaging characteristics of IMTs have been variable and nonspecific[13-15].

      In retrospective studies, a higher uptake of 18F-FDG in the SCV of subjects with lower BMI29–31,36 and less adiposity was observed30. Orava et al.37 furthered these initial findings in a prospective study wherein lean subjects exhibited heightened cold-induced BAT glucose uptake and blood flow compared to their obese counterparts.

      However, it must be acknowledged that both approaches may lead to false positive CR due to limitations of FDG-PET and biopsy resolution/sensitivity. Note: A ‘positive’ FDG-PET scan lesion means one which is FDG avid with an uptake greater than twice that of the surrounding tissue on the attenuation corrected image. 11.1.4 Response Criteria
