  1. 1. Quantitative imaging with PET : performance and applications of 76Br, 52Fe, 110mIn and 134La

    Författare :Mark Lubberink; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PET; Positron Emission Tomography; Quantitative Imaging; bromine; iron; indium; lanthanum; Onkologi; Oncology; Onkologi; Oncology; Onkologi;

    Sammanfattning : The use of positron emission tomography (PET) has so far mainly been limited to a few nuclides with short half-lives such as 11C and 18F. Certain applications require nuclides with longer half-lives, such as 76Br and 52Fe. LÄS MER

    Sammanfattning : Virtually all the magnetic resonance imaging (MRI) signal of a human originates from water and fat molecules. By utilizing the property chemical shift the signal can be separated, creating water- and fat-only images. LÄS MER

  4. 3. On potentials and limitations of perfusion MRI in neurological disorders

    Författare :Markus Fahlström; Mark Lubberink; Adam Espe Hansen; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurological disease; MRI; Perfusion; 15O-water PET; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Cerebral perfusion outlines several parameters which describe the status of cerebral haemodynamics. Numerous neurological diseases affect cerebral perfusion, thus the importance of diagnostic measurements. LÄS MER

  5. 4. ­­­Visual assessment of perfusion and metabolism in neurodegenerative dementia

    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

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

    Författare :Kerstin Heurling; Mark Lubberink; Jens Sörensen; Julie Price; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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
