  1. 1. Development and evaluation of an independent system for absorbed dose calculations in radiotherapy

    Författare :Stefan Johnsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; tomography; medical instrumentation; radiology; Clinical physics; cancer; Cytologi; onkologi; cancerology; oncology; Cytology; PDA; mini-phantom; in-air equivalence; primary kerma; transmission measurement; stopping power ratio; entrance dose; beam quality; quality control; error prevention; monitor unit calculation; radiation therapy; dose calculation;

    Sammanfattning : The aim of this work was to develop, implement and evaluate an independent system with which to calculate the absorbed dose, delivered by high-energy X-ray beams, to the prescription point and the depth of dose maximum. The introduction of such a system in the clinical routine may help ensure high-quality treatment and avoidance of errors which may jeopardise the clinical outcome of the treatment (i. LÄS MER

  3. 2. Peptide Receptor Radionuclide Therapy in Neuroendocrine Neoplasms : Aspects of tumour characteristics, receptor recycling and peptide mass

    Författare :Ulrika Jahn; Anders Sundin; Mark Lubberink; Ulrike Garske-Román; Mona-Elisabeth Rootwelt-Revheim; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroendocrine tumors; Peptide receptor radionuclide therapy PRRT ; Peptide; Small-Intestinal; Pancreatic; Dosimetry; Somatostatin receptor;

    Sammanfattning : Neuroendocrine neoplasm (NEN) can arise in any part of the body, but most commonly in the lungs, bronchi, and the gastrointestinal tract including the pancreas. They combine neuroendocrine and tissue-of-origin-specific characteristics; explaining different symptoms depending on the organ of origin. LÄS MER

  4. 3. Molecular Radionuclide Imaging Using Site-specifically Labelled Recombinant Affibody Molecules : Preparation and Preclinical Evaluation

    Författare :Sara Ahlgren; Vladimir Tolmachev; Anna Orlova; Göran Hedenstierna; Joachim Feldwisch; Raymond Reilly; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molecular radionuclide imaging; Affibody molecules; HER2; cancer detection; radiolabelling; technetium; indium; cobalt; SPECT; PET; Oncology; Onkologi; Diagnostic radiology; Diagnostisk radiologi; Radiation biology; Strålningsbiologi; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Radionuclide molecular imaging is an emerging multidisciplinary technique that is used in modern medicine to visualise diseases at cellular and molecular levels. This thesis is based on five papers (I-V) and focuses on the development of site-specific radiolabelled recombinant anti-HER2 Affibody molecules and preclinical evaluations in vitro and in vivo of the labelled conjugates.

  5. 4. Statistical methods in medical image estimation and sparse signal recovery

    Författare :Fekadu Lemessa Bayisa; Jun Yu; Ottmar Cronie; Henning Omre; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Computed tomography; magnetic resonance imaging; Gaussian mixture model; skew-Gaussian mixture model; hidden Markov random field; hidden Markov model; supervised statistical learning; synthetic CT images; pseudo-CT images; spike and slab prior; adaptive algorithm;

    Sammanfattning : This thesis presents work on methods for the estimation of computed tomography (CT) images from magnetic resonance (MR) images for a number of diagnostic and therapeutic workflows. The study also demonstrates sparse signal recovery method, which is an intermediate method for magnetic resonance image reconstruction. LÄS MER

  7. 5. Interventions for portal hypertension in patients with portal vein occlusion and possible effects of a stent-graft on hepatic circulation

    Författare :Inger Keussen; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; recanalization; TIPS; hepatic vein occlusion; children; Key words: portal vein occlusion; scintigraphy; stent; portal hypertension;

    Sammanfattning : Symptomatic portal hypertension (PH), is often treated by transjugular intrahepatic portosystemic shunt (TIPS). Patients with PH, caused by prehepatic portal vein occlusion, require recanalization with stent or stent-graft often followed by additional TIPS. LÄS MER
