Statistical methods for mapping kinetics together with associated uncertainties in long field of view dynamic PET studies
Positron Emission Tomography (PET) is an essential diagnostic imaging technique in clinical care settings, as well as in medical research. It plays a crucial role in diagnosis, prognosis, treatment planning, and clinical decision-making. PET imaging, a well-established radio-tracer imaging …

Changes in cerebral glucose metabolism in patients with Parkinson’s disease with dementia after cholinesterase inhibitor therapy
… on brain images. We performed serial 18FFDG PET studies in patients with PDD before and after ChEI therapy. METHOD: We investigated 11 patients with clinical diagnosis of PDD. Patients were treated with either donepezil or galantamine. End point was when patients were treated for at least 3 …

Emotion, Depression, and Asymmetric Brain Function
Although numerous electroencephalography (EEG) studies have shown that depression is associated with abnormal functional asymmetries in frontal cortex, functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET) studies have largely failed to identify specific brain regions …

Gifts from Afar: The Creation of an Imperial Lapdog in Tang–Song China
… a significant gap in the fields of sinology and pet studies by exploring pre-modern Chinese pet-keeping practices in detail for the first time in either discipline. More specifically, this thesis centres on the social and economic practice of lapdog-keeping across the seventh to twelfth …

Untersuchung zur Stimmerkennung bei aphasischen und nicht-aphasischen Patienten
… sitting behind his hedge. Previous (fMRI-, PET-) studies suggest that impairment of voice recognition can be caused by damage to the parietal as well as the temporal regions of the right hemisphere. The objective of our current study is to determine the performance of left brain damaged …

Vergleich von Positronen-Emissionstomographie mit (18F-)2-Fluor-2-Deoxy-D-Glucose und Computertomographie zum Staging maligner Lymhome
… examination (positrone-emission-tomography, PET) with 18F-Fluorodeoxy-glucose. Methods: CT and FDG-PET studies of 65 patients with histological confirmed malignant lymphoma as primary were evaluated retrospectively first by visual examination and afterwards by quantification. FDG-PET …

Biophysical Considerations in the Precision of Quantitative <sup>18</sup>F-FDG PET/CT
… are critical components of such imaging studies. A variety of both biological and physical factors affect these qualities in significant ways. As PET technology continues to evolve, an understanding of these effects becomes essential to the continued usefulness of PET in clinical …

CHOLINERGIC CONTRIBUTIONS TO EMOTION REGULATION
Theories based on clinical and neuroanatomical studies implicate the muscarinic cholinergic system in normal and pathological emotion regulation. Emotional and sensory experiences can be induced with intravenous administration of the local anesthetic procaine hydrochloride, which selectively …

Heading Disorientation in Amnestic Mild Cognitive Impairment is Correlated with Hypometabolism in the Posterior Cingulate Cortex
… the test have not yet been replicated in other studies. In our study, using statistical parametric mapping (SPM) analysis we aimed to investigate anatomical correlates of both part A and B of the CPT in FDG-PET studies of patients with amnestic mild cognitive impairment (aMCI). METHODS: A total …

Onderzoek naar het werkingsmechanisme van acamprosaat, een geneesmiddel tegen alcoholverslaving, met behulp van een radiotracer voor positron emissie tomografie
… positron emissie tomografie of kortweg PET. Met behulp van deze beeldvormingstechniek is het mogelijk om het biologisch gedrag van een radioactief gemerkte molecule te onderzoeken in de hersenen van levende wezens, zonder de normale werking van het CZS te verstoren. Het doel van het …

Myocardial Perfusion Imaging With Rb-82 PET
… wall thickening. Positron emission tomography (PET) and single photon emission computed tomography (SPECT) are two modalities that can be used to quantify the left global and regional perfusion at rest and stress. While PET and SPECT rely on similar principles to produce images, important …

Developing a selective sphingosine-1-phosphate-5 (s1p5) radiotracer to image oligodendrocytes using preclinical positron emission tomography (PET)
… to develop novel Positron Emission Tomography (PET) ligands to specifically bind to oligodendrocytes in the central nervous system in vivo. The ligands target the sphingosine-1-phosphate-5 (S1P5) receptor as a potential marker of oligodendrocyte function with PET. The ligands selected (TEFM180 …

THE EXPLORATION OF THE VALIDITY OF QUANTITATIVE 2-DEOXY-2-[FLUORINE-18] FLUORO-D-GLUCOSE (18F-FDG) POSITRON EMISSION TOMOGRAPHY/COMPUTED TOMOGRAPHY (PET/CT) TO ASSESS LUNG INFLAMMATION
… emission tomography/computed tomography (PET/CT) is an imaging modality capable of providing functional and molecular imaging through detection of trace quantities of a radioactive tracer. 18F-FDG is the most widely available tracer and in several small studies has been used to investigate …
