MRI is commonly used to determine the location and extent of cerebral gliomas. We investigated whether the diagnostic accuracy of MRI could be improved by the additional use of PET with the amino acid O-(2-[18F]fluoroethyl)-l-tyrosine (FET). In a prospective study, PET with FET and MRI was performed in 31 patients with suspected cerebral gliomas. PET and(More)
UNLABELLED In the diagnosis of giant cell arteritis (GCA) with aortic involvement, (18)F-FDG PET has been demonstrated to be a powerful tool. No other imaging method is able to directly detect acute inflammation within the aortic wall. However, because GCA is a rare PET indication, the assessment of GCA with (18)F-FDG PET remains difficult and highly(More)
OBJECTIVES Stem cell therapy may be useful in chronic myocardial infarction (MI); this is conceivable, but not yet demonstrated in humans. BACKGROUND After acute MI, bone marrow-derived cells improve cardiac function. METHODS We treated 18 consecutive patients with chronic MI (5 months to 8.5 years old) by the intracoronary transplantation of autologous(More)
In working memory (WM), functional imaging studies demonstrate cerebellar involvement indicating a cognitive role of the cerebellum. These cognitive contributions were predominantly interpreted as part of the phonological loop within the Baddeley model of WM. However, those underlying investigations were performed in the context of visual verbal WM which(More)
Various factors are discussed in the pathophysiology of anxiety disorders, including dysfunctions of the (DA)ergic, serotonin (5-HT)ergic and GABAergic system. We assessed the contribution of the individual synaptic constituents by subjecting all available in vivo imaging studies on patients with anxiety disorders to a retrospective analysis. On a total of(More)
OBJECT The purpose of this study was to determine the predictive value of [18F]fluoroethyl-L-tyrosine (FET)-positron emission tomography (PET) and magnetic resonance (MR) spectroscopy for tumor diagnosis in patients with suspected gliomas. METHODS Both FET-PET and MR spectroscopy analyses were performed in 50 consecutive patients with newly diagnosed(More)
This review gives an overview of those in vivo imaging studies on synaptic neurotransmission, which so far have been performed on patients with mental and affective disorders. Thereby, the focus is on disease-related deficiencies within the functional entities of the dopaminergic, serotonergic, cholinergic, histaminergic, glutamatergic, or GABAergic(More)
High-alexithymic individuals are characterized by an impaired ability to identify and communicate emotions whereas low-alexithymic individuals have a wide-ranging ability to deal with emotions. This study examined the hypothesis that valence and arousal modifications of emotional stimuli differentially modulate cortical regions in high-alexithymic and(More)
UNLABELLED In vivo molecular imaging of pre- and postsynaptic nigrostriatal neuronal degeneration and sympathetic cardiac innervation with SPECT is used to distinguish idiopathic Parkinson disease (PD) from atypical parkinsonian disorder (APD). However, the diagnostic accuracy of these imaging approaches as stand-alone procedures is often unsatisfying. The(More)
This review gives an overview of those in vivo imaging studies on synaptic neurotransmission, which so far have been performed on patients with movement disorders and/or dementia. Thereby, the focus is on disease-related deficiencies within the functional entity of the dopaminergic, serotonergic, cholinergic, glutamatergic, GABAergic or opioid synapse. In(More)
