In order to associate metabolic patterns with pathophysiological and compensatory mechanisms, we combined resting state [18F]FDG-PET (to demonstrate brain metabolism in awake animals), [18F]FDOPA-PET (dopamine depletion severity) and gait analysis in a unilateral 6-hydroxydopamine rat model.
Raichle et al., 2001 [8] used quantitative positron emission tomography (PET) to demonstrate the existence of such a baseline state of human brain function that is remarkably uniform in the awake resting state and they used the term baseline default mode of brain function to describe activity in the regions involved.
Various groups have reported on the ability of PET to demonstrate unsuspected disease or help confirm equivocal lesions[ 123, 132 ].
Volkow et al. used positron emission tomography (PET) to demonstrate that extracellular DA increases in proportion to the level of DAT blockade, and the rate of DA release by cell firing.
Further studies, including comparisons between F-FLT and F-FDG uptake levels in mouse or rat allograft tumor models and in patients, are necessary to compare the potentials of F-FLT PET and F-FDG PET and to demonstrate the advantages of F-FLT PET for the early and accurate detection of the antiproliferative effect of gefitinib.
This may explain the failure of some PET studies to demonstrate changes in [11C]raclopride binding upon nicotine administration [14, 15].
In the present study, we conducted DCE-CT and PET scanning to demonstrate the utility of non-invasive imaging biomarkers to longitudinally assess muscle regeneration/degeneration in two murine models of DMD.
For example, Hirvonen and colleagues (2013) have used PET imaging to demonstrate that alcoholics have profound deficits in the levels of cannabinoid receptor 1 (CB1) in the cortex, and particularly in the frontal cortex, supporting further efforts to pharmacologically manipulate cannabinoid signaling in people with AUD.
During Hurricane Sandy, for example, they spread a fake rumour about African-Americans looting people's homes and stealing domestic pets – an attempt to demonstrate how shoddy mainstream reporting on African-Americans can be.

Other PET studies failed to demonstrate perfusion abnormalities in patients with migraine without aura during an attack; however the focus of their investigation was the brainstem [ 64, 86].
