FDG-PET和MRI亚型之间的比较包括以下三个方面:1)在一种模态下进行亚型划分,并将其相应的萎缩/低代谢模式映射到另一种模态;2)通过FDG-PET和MRI得到的亚型频率;3)各个亚型分配之间的交叉情况。采用W分数评估FDG-PET各亚型的局部萎缩模式和MRI各亚型的局部低代谢模式。W分数通过从认知正常数据中减去均值并除以标准差...
Urgent [18F]FDG PET/CT brain scans were performed on 7 of the 9 ICANS patients, showing diffuse cortical hypometabolism compatible with encephalopathy in 5 (5/7) and no significant findings in 2/7. At the 30-day post-treatment evaluation, complete normalization was observed in 2/5 patients,...

According to current guidelines from 2005 (CBO) functional brain imaging by PET-scan of the brain has no place in the analysis of a syndrome. Differential diagnosis between and other causes of remains important because there are differences in natural course and treatment. Here we present three ...
Background: The authors reviewed the two most common current uses of brain 18F-labeled fluoro-2-deoxyglucose positron emission tomography (FDG-PET) at a large academic medical center. For epilepsy patients considering surgical management, FDG-PET can help localize epileptogenic lesions, discriminate be...
Introduction: We have been using a method of paired FDG PET scans immediately prior to and following infusion with psychoactive compounds as a means of assessing regional effects of these drugs on brain metabolism. We wished to test the validity of this method by use of placebo (PBO) ...
(APS), including patients with progressive supranuclear palsy (PSP), multiple system atrophy (MSA), and corticobasal degeneration (CBD), who underwent [(18)F]fluorodeoxyglucose (FDG)-PET and postsynaptic D2 receptor [(123)I]iodobenzamide (IBZM)-SPECT imaging at baseline to distinguish APS from...

Although recent studies identified brain areas which are involved in short term activation of the sympathetic nervous system, little is known about brain mechanisms which generate the individual variability of basal autonomic activity. In this fluorodeoxyglucose positron emission tomography study (FDG–PET)...
