  2. 1. Internal Dosimetry Development and Evaluation of Methods and Models

    Author : Lena M Jönsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; crypt cells; intestine; radionuclide; scintillation camera; sestamibi; activity quantification; conjugate view method; Monte Carlo simulation; internal dosimetry; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; medicinsk instrumentering; radiologi;

    Abstract : Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. READ MORE

  5. 3. Multiparametric MRI for evaluation of tumour treatment response : Studies of 177Lu-octreotate therapy of neuroendocrine tumour

    Author : Mikael Montelius; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; Functional imaging; IVIM; MRI; DWI; DCE; histology; 177Lu-octreotate; small intestine neuroendocrine tumour; NET; diffusion; perfusion; semi-quantitative; proteomics; ionizing radiation; biology; imaging biomarker;

    Abstract : Clinical assessment of tumour response to treatment largely relies on estimates of tumour size by, e.g., measuring the largest tumour diameters on magnetic resonance (MR) or computed tomography (CT) images, weeks or months after treatment. READ MORE

  6. 4. Lutetium-177-octreotate treatment of small intestine neuroendocrine tumors - Radiation biology as basis for optimization

    Author : Johan Spetz; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Peptide receptor radionuclide therapy; PRRT; somatostatin receptors; SSTR; midgut carcinoid; radiogenomics;

    Abstract : Patients with neuroendocrine tumors (NETs) often have metastatic spread at the time of diagnosis. NETs frequently express somatostatin receptors (SSTR) that can be targeted by radiolabeled somatostatin analogs (e.g. 177Lu-octreotate). READ MORE

  7. 5. Intestinal barrier function in health and disease

    Author : Pernilla Nejdfors; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VIP.; PACAP; secretion; ion transport; urine reservoir; radiation therapy; ulcerative colitis; macromolecules; dextran; mannitol; Ussing chamber; Intestinal permeability; mucosa; Animal physiology; Djurfysiologi; Physiology; Fysiologi;

    Abstract : The intestinal epithelium has the dual function of absorbing nutrients and water as well as being a barrier to potentially harmful substances such as macromolecules and bacteria. In the present thesis the barrier function of the intestinal mucosa was studied in vitro in Ussing diffusion chambers. READ MORE
