  1. 1. Positron Emission Tomography and Magnetic Resonance Techniques in Diabetes

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lina Carlbom; Uppsala universitet.; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; Magnetic resonance imaging; Magnetic resonance spectroscopy; Type 1 diabetes; Type 2 diabetes; PET MR; Pancreas transplantation; Perfusion; Radiology; Radiologi;

    Sammanfattning : In order to further advance the field of diabetes research there is a great need for establishing validated non-invasive quantitative techniques to study the pancreas and other tissues of importance for blood glucose regulation. The general aim of this thesis was to explore magnetic resonance techniques and positron emission tomography as such tools. LÄS MER

  2. 2. Preoperative MRI and PET in suspected low-grade gliomas Radiological, neuropathological and clinical intersections

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anna Falk Delgado; Uppsala universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low-grade glioma; MRI; PET; FA; MD; Perfusion; Diffusion; Neuropathology; Oligodendroglioma; Astrocytoma; PET; tractography; DTI; DTT; Radiology; Radiologi;

    Sammanfattning : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. LÄS MER

  3. 3. ­­­Visual assessment of perfusion and metabolism in neurodegenerative dementia

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :David Fällmar; Uppsala universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dementia; Neurodegenerative; Brain imaging; Diagnostics; Neuroradiology; Neuroimaging; Demens; Neurodegenerativ; Hjärnavbildning; diagnostik; Neuroradiologi; Neuroimaging; Radiology; Radiologi;

    Sammanfattning : A worldwide demographic shift is currently occurring, with rapidly increasing numbers of elderly individuals. Since the incidence of neurodegenerative disease generally increases with age, this entails an increase in dementia prevalence. LÄS MER

  4. 4. Characterization of [18F]flutemetamol binding properties A β-amyloid PET imaging ligand

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Kerstin Heurling; Uppsala universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography PET ; molecular imaging; amyloid; tracer validation; Radiology; Radiologi;

    Sammanfattning : The criteria for diagnosing Alzheimer’s disease (AD) have recently been revised to include the use of biomarkers for the in vivo presence of β-amyloid, one of the neuropathological hallmarks of AD. Examples of such biomarkers are positron emission tomography (PET) β-amyloid specific ligands, including [18F]flutemetamol. LÄS MER

  5. 5. Towards Clinical Implementation of Dynamic Positron Emission Tomography in Neurodegenerative Diseases

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :My Jonasson; Uppsala universitet.; [2018]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET; Molecular imaging; Quantification; Kinetic modelling; Parametric images; Alzheimer’s disease; Parkinson’s disease; Radiology; Radiologi;

    Sammanfattning : Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the two most common neurodegenerative disorders worldwide. Positron emission tomography (PET), together with suitable biomarkers, can aid in the clin-ical evaluation as well as in research investigations of these diseases. LÄS MER
