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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mark Lubberink; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PET; Positron Emission Tomography; Quantitative Imaging; bromine; iron; indium; lanthanum; Onkologi; MEDICINE Surgery Oncology; MEDICIN Kirurgi Onkologi; Oncology; onkologi;

    Abstract : 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. READ MORE

    Abstract : Schizophrenia is a group of disorders with a worldwide lifetime prevalence of 0.85%. Thefunctional outcome of the disorder seem stable from the first systematic outcome studies to thepresent day, and vary only with changes in diagnostic criteria. READ MORE

  5. 3. Affibody Molecules for PET Imaging

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joanna Strand; Tolmachev Vladimir; Sten Nilsson; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Affibody molecules; Molecular imaging; PET; Radiolabelling; HER2; PDGFRβ; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

    Abstract : Optimization of Affibody molecules would allow for high contrast imaging of cancer associated surface receptors using molecular imaging. The primary aim of the thesis was to develop Affibody-based PET imaging agents to provide the highest possible sensitivity of RTK detection in vivo. READ MORE

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Kayo Takahashi; Mats Bergström; Bengt Långström; Yasuyoshi Watanabe; Torbjörn Bäckström; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aromatase; brain; molecular imaging; PET; [11C]Vorozole; amygdala; hypothalamus; anabolic-androgenic steroids; abuse; [18F]Vorozole analogs; MEDICINE Morphology; cell biology; pathology Cell biology Neuroscience; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi Neurovetenskap;

    Abstract : Aromatase is an enzyme that facilitates the conversion of androgens to estrogens and may play a role in mood and mental status. The main theme of this thesis is the imaging of brain aromatase by use of the PET technique. The PET tracer for aromatase, 11C-labeled vorozole (VOZ) was developed and evaluated by with in vitro and in vivo methods. READ MORE
