    Sammanfattning : IntroductionPaper I: An Artificial Neural Network (ANN) was constructed to identify ST Elevation Myocardial Infarction (STEMI) and predict the need for Percutaneous Coronary Intervention (PCI). Paper II, III and IV: Studies suggest that O2 therapy may be harmful in STEMI patients. LÄS MER

  3. 2. Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT

    Författare :Susanna Jakobson Mo; Katrine Åhlström Riklund; Anne Larsson Strömvall; Lars Forsgren; Rimma Axelsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; SPECT; 123I-FP-Cit; 123I-IBZM; dopamine; parkinsonism; Parkinson’s disease; multiple system atrophy; progressive supranuclear palsy; Radiology; radiologi;

    Sammanfattning : Background: Single photon emission computed tomography (SPECT) with dopamine transporter (DAT) and dopamine D2 receptor (D2R) ligands can visualise the integrity of the nigrostriatal dopamine system. Parkinson’s disease (PD) and the atypical parkinsonian diseases (APD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), have similar symptoms and dopamine depletion, but differ in pharmacological response and prognosis.

  4. 3. Studies of Nuclear Fuel by Means of Nuclear Spectroscopic Methods

    Författare :Peter Jansson; Roland Carchon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; irradiated nuclear fuel; nuclear spectroscopy; tomography; safeguard; Strålningsvetenskap; Radiation biology; Strålningsbiologi; Kärnfysik; Nuclear Physics;

    Sammanfattning : The increasing demand for characterization of nuclear fuel, both from an operator and authority point of view, motivates the development of new experimental and, preferable, non-destructive methods. In this thesis, some methods based on nuclear spectroscopic techniques are presented. LÄS MER
