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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sara Sohlberg; Uppsala universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

    Detta är en avhandling från Stockholm : KTH

    Författare :Isabelle Dussauge; KTH.; [2008]
    Nyckelord :HUMANIORA; HUMANITIES; HUMANITIES and RELIGION History and philosophy subjects History subjects History of technology; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Historieämnen Teknikhistoria; 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;

    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

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Lars Wigström; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Sergey Manuilov; KTH.; [2011]
