  1. 1. Quantitative methods for tumor imaging with dynamic PET

    Author : Ida Häggström; Anne Larsson; Mikael Karlsson; Lennart Johansson; Jens Sörensen; Magnus Dahlbom; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Dynamic positron emission tomography; PET; tumor imaging; compartment modeling; Monte Carlo; radiofysik; radiation physics;

    Abstract : There is always a need and drive to improve modern cancer care. Dynamic positron emission tomography (PET) offers the advantage of in vivo functional imaging, combined with the ability to follow the physiological processes over time. READ MORE

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

    Author : Mark Lubberink; Uppsala universitet; []
    Keywords : 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;

    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

  3. 3. PET applications in schizophrenia : Functional and pharmacological dopamine studies

    Author : Ola Gefvert; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Schizophrenia; PET; dopamine synthesis rate; dopamine D2 receptor occupancy; atypical antipsychotics; quetiapine; risperidone microsphere depot; Neurovetenskap; Neurology; Neurologi; Psychiatry; psykiatri;

    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

  4. 4. Affibody Molecules for PET Imaging

    Author : Joanna Strand; Tolmachev Vladimir; Sten Nilsson; Uppsala universitet; []
    Keywords : 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

  5. 5. Radiolabeled acetate PET in oncology imaging : studies on head and neck cancer, prostate cancer and normal distribution

    Author : Aijun Sun; Jens Sörensen; Silvia Johansson; Mikael Karlsson; Katrine Åhlström Riklund; Ingela Turesson; Heikki Minn; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11C-acetate; 18F-fluoroacetate; PET; head and neck cancer; staging; delineating tumor volume; clearance rate; perfusion; RT; treatment outcome; benign and malignant lymph node; prostate cancer; normal distribution; Oncology; Onkologi; onkologi; Oncology;

    Abstract : The use of positron emission tomography (PET) for imaging in oncology has grown rapidly in recent years. 2-[18F]-fluorodeoxyglucose (FDG) is the most common tracer of PET, although drawbacks exist. READ MORE
