  1. 11. FDG PET and MRI as biomarkers of Tau pathology in Alzheimer’s disease

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Putu Ayuwidia Ekaputri; [2021]
    Keywords : Alzheimer’s disease; fdg pet; mri; tau pet; tau pathology;

    Abstract : Fluorodeoxyglucose Positron Emission Tomography (FDG PET) and Magnetic Resonance Imaging (MRI) are commonly used in a clinical setting as an examination in Alzheimer’s Disease (AD) patients. FDG PET is an imaging tool to evaluate hypometabolism; meanwhile, the MRI observes the brain volume. READ MORE

  3. 12. Characterization of Center-of-Mass and Rebinning in Positron Emission Tomography with Motion

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Linder Hugo; [2021]
    Keywords : positron emission tomography; center of mass; motion correction;

    Abstract : Medical molecular imaging with positron emission tomography (PET) is sensitive to patient motion since PET scans last several minutes. Despite advancements in PET, such as improved photon-pair time-of-flight (TOF) difference resolution, motion deformations limit image resolution and quantification. READ MORE

  4. 13. Regional atrophy correlates of domain-specific episodic memory in early Alzheimer’s disease

    University essay from Lunds universitet/Institutionen för psykologi

    Author : Hannah Baumeister; [2021]
    Keywords : Alzheimer’s disease; episodic memory; amyloid-β; tau; atrophy; neurodegeneration; mnemonic discrimination; response bias; Medicine and Health Sciences;

    Abstract : Alzheimer’s disease (AD) is characterized by amyloid-β (Aβ) and tau depositions as well as neurodegeneration, and is typically accompanied by a progressive decline in episodic memory. Previous research proposes two neural memory networks that process different stimulus domains. READ MORE

  5. 14. Prioritization of Informative Regions in PET Scans for Classification of Alzheimer's Disease

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Fredrik Mårtensson; Erik Westberg; [2021]
    Keywords : ;

    Abstract : Alzheimer’s Disease (AD) is a widespread neurodegenerative disease. The disease causes brain atrophy, resulting in memory loss, decreased cognitive ability, and eventually death. There is currently no cure for the disease, but treatment may delay the onset. Therefore, it is crucial to detect the disease at an early stage. READ MORE

  6. 15. Differences in tumor volume for treated glioblastoma patients examined with 18F-fluorothymidine PET and contrast-enhanced MRI

    University essay from Umeå universitet/Institutionen för fysik

    Author : Karolina Hedman; [2020]
    Keywords : PET MRI; positron emission tomography; magnetic resonance imaging; brain tumor; glioblastoma; image segmentation; adaptive thresholding; feature extraction; radiotracer; gadolinium; image processing; image analysis;

    Abstract : Background: Glioblastoma (GBM) is the most common and malignant primary brain tumor. It is a rapidly progressing tumor that infiltrates the adjacent healthy brain tissue and is difficult to treat. Despite modern treatment including surgical resection followed by radiochemotherapy and adjuvant chemotherapy, the outcome remains poor. READ MORE
