  1. 6. Computational patient models for simulation of dynamic gamma-camera imaging : Application to renography and peptide receptor radionuclide therapy

    Författare :Gustav Brolin; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; Gamma camera; Renography; Radionuclide therapy; Internal dosimetry; Pharmacokinetics;

    Sammanfattning : Many nuclear medicine investigations rely on gamma-camera imaging to study and quantify the distribution of radiopharmaceuticals or radionuclides in the patient as a function of time. This is typically used for diagnostic studies of physiological functions or for calculation of absorbed doses following radionuclide therapy. LÄS MER

  3. 7. Methods for image-based dosimetry and radiobiological modelling in radionuclide therapy

    Författare :Johan Gustafsson; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radionuclide therapy; dosimetry; biologically effective dose; 177Lu-DOTATATE;

    Sammanfattning : In radionuclide therapy (RNT), radioactive pharmaceuticals are administered for therapeutic purposes. Dosimetry, i.e. the estimation of the absorbed dose to various targets, can potentially lead to a better understanding of the therapeutic effects in RNT and allow for individualization of the therapy.

  4. 8. Methods for quantitative analysis of myocardial perfusion SPECT : validated with magnetic resonance imaging, phantom studies and expert readers

    Författare :Helen Fransson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segmentation; Quantification; Spline; Image registration; Cardiac image analysis; Myocardial perfusion SPECT;

    Sammanfattning : In this thesis, methods for automated analysis of myocardial perfusion single photon emission computer tomography (myocardial perfusion SPECT, MPS) images have been successfully developed and evaluated. MPS images show the perfusion of the myocardium and are used for diagnosing patients with suspected ischemic heart disease. LÄS MER

  5. 9. Detection of Myocardial Ischemia using Real-Time Myocardial Contrast Echocardiography

    Författare :Petri Gudmundsson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial contrast echocardiography; MCE; stress echocardiography; adenosine; perfusion; real-time; visual; quantative; wall motion; power modulation; bedside; SPECT; coronary insufficiency;

    Sammanfattning : Diagnostisering av syrebrist i hjärtmuskeln med hjälp av kontrastförstärkt ultraljudsundersökning av hjärtmuskelns genomblödning. Ultraljudsundersökning av hjärtat (ekokardiografi) används mycket inom hjärtsjukvården idag, oftast för att utreda hjärtats och hjärtklaffarnas anatomi och funktion. LÄS MER

  7. 10. Early ventilatory management and lung function in the immature newly born. Experimental studies in lambs

    Författare :Jonas Ingimarsson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensive care; Anestesiologi; intensivvård; Anaesthesiology; newborn.; animals; lung recruitment; resuscitation; respiratory distress syndrome; pulmonary surfactants;

    Sammanfattning : Using an animal model, the thesis explores how the initial ventilation of the lungs, and surfactant therapy, should best be managed after premature birth. Material and measurements: The studies were made in newborn lambs delivered by cesarean section. LÄS MER
