  1. 1. Technomedical Visions Magnetic Resonance Imaging in 1980s Sweden

    University dissertation from Stockholm : KTH

    Author : Isabelle Dussauge; KTH.; [2008]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University dissertation from Linköping : Linköpings universitet

    Author : Lars Wigström; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2003]

    Abstract : 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. READ MORE

  3. 3. Diffusion tensor magnetic resonance imaging of the brain Tractography analysis with application in healthy individuals and patients

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johanna Mårtensson; Uppsala universitet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; Diffusion Tensor Imaging; Tractography; white matter tracts; Radiology; Radiologi;

    Abstract : In study 1, thirty-eight healthy controls were used for optimization of the method. Fifteen patients with progressive supranuclear palsy and an equal number of age-matched healthy controls underwent diffusion tensor MRI and were then investigated and compared groupwise. READ MORE

  4. 4. Magnetic Resonance Imaging in Legg-Calvé-Perthes Disease

    University dissertation from Department of Radiology, Lund University

    Author : Peter Hochbergs; Lunds universitet.; Lund University.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; Histology; Metaphysis; Synovitis; Necrosis; Osteotomy; Arthrography; Magnetic Resonance Imaging; Legg-Calvé-Perthes Disease; Pediatrics; Hip; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology;

    Abstract : The aims of this study were: to compare the cartilaginous outline of the femoral head obtained on arthrograms with those on MR images and to correlate it to the bony head outlines on conventional radiograps; to study early, postoperative cartilaginous and bony remodeling of the femoral head, after proximal femoral varus derotation extension osteotomy, with MR imaging and conventional radiography; to describe signal abnormalities on MR images in the femoral epiphysis, their location, extent and restitution over time; to evaluate the degree and persistence of synovitis in the hip joint by MR imaging; to analyze the metaphyseal histology and to correlate it to the signal intensity on the MR images in the corresponding biopsy region. Results and conclusions: MR imaging and arthrography define the shape of the femoral head cartilage equally well. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sara Sohlberg; Uppsala universitet.; [2015]
    Keywords : 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;

    Abstract : 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. READ MORE
