  2. 2. Placental Function : An Epidemiological and Magnetic Resonance Study

    Författare :Sara Sohlberg; Anna-Karin Wikstrom; Matts Olovsson; Ajlana Mulic-Lutvica; Johan Wikström; Karel Marsal; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; body height; body mass index; early preeclampsia; late preeclampsia; magnetic resonance imaging; placenta; perfusion; IVIM; risk factors; energy metabolism; magnetic resonance spectroscopy; 31P-MRS; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Placental function is central for normal pregnancy and in many of the major pregnancy disorders. We used magnetic resonance imaging techniques to investigate placental function in normal pregnancy, in early and late preeclampsia and in intrauterine growth restriction. LÄS MER

  3. 3. Technomedical Visions : Magnetic Resonance Imaging in 1980s Sweden

    Författare :Isabelle Dussauge; Arne Kaijser; Pär Blomkvist; Eva Åhrén; Anne Beaulieu; KTH; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; anatomy; body; NMR; psychiatry; radiology; representations; Sweden; visual studies; history of medicine; history of technology; laboratory science; magnetic resonance; mediation; medical gaze; medical imaging; MRI; History of technology; Teknikhistoria;

    Sammanfattning : The medical imaging technology called MRI (magnetic resonance imaging) stems from a blind measurement technology which was further developed in research and practice to enable seeing into the inner body. Vision with MRI was open-ended, and it was developed and tamed in a context of fragmented medical perspectives on the body and on technology. LÄS MER

  4. 4. Multidimensional magnetic resonance imaging : new methods for analysis of cardiovascular dynamics

    Författare :Lars Wigström; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Cardiovascular flow and motion occur in three-dimensional (3D) space and vary dynamically over the cardiac cycle. The description of these complicated patterns using non-invasive imaging requires new tools for data acquisition, processing and visualization. LÄS MER

  5. 5. Ferromagnetic resonance in films with growth induced anisotropy

    Författare :Sergey Manuilov; Alex Grishin; Boris Kalinikos; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ferromagnetic resonance; magnetic anisotropy; single-ion anisotropy model; ferrites; magnetic epitaxial films; magnetostatic waves; pulsed laser deposition; magnetic alloys; domains; domain wall transformations;

    Sammanfattning : This thesis discusses two different magnetic materials: epitaxial yttrium iron garnet (YIG) and heteromorphous CoFeB-SiO2 films. YIG films were grown by pulse laser deposition (PLD) techniques onto gadolinium gallium garnet (GGG) substrates of (111) and (001) crystal orientations. LÄS MER
