    Sammanfattning : Contrast-enhanced magnetic resonance angiography (CE-MRA) is a diagnostic method for imaging of vascular structures based on nuclear magnetic resonance. Vascular enhancement is achieved by injection of a contrast medium (CM). LÄS MER

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

    Detta är en avhandling från Stockholm : KTH

    Författare :Isabelle Dussauge; KTH.; [2008]
    Nyckelord :HUMANIORA och RELIGIONSVETENSKAP; HUMANITIES and RELIGION; 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

  5. 4. On contrast-enhanced magnetic resonance angiography of the aortoiliac arteries

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Wikström; Uppsala universitet.; [2001]
    Nyckelord :MEDICIN; MEDICINE; Oncology; Magnetic resonance imaging; Magnetic resonance angiography; Contrast media; Arteriosclerosis; Iliac artery; Blood pressures; Onkologi; Radiology; radiologi;

    Sammanfattning : In contrast-enhanced magnetic resonance angiography (CE-MRA),vascular signal is produced by the acquisition of a T1-weighted magnetic resonance imaging scan while the presence of a contrast agent induces a low T1 in blood. In this thesis,CE-MRA of the aortoiliac arteries was evaluated. LÄS MER

  7. 5. Broadband Ferromagnetic Resonance Spectrometer : Instrument and Applications

    Detta är en avhandling från Kista : Mikroelektronik och informationsteknik

    Nyckelord :ferrites; thin films; ferromagnetic resonance; microwaves; FMR spectrometer; magnetic anisotropy; magnetostatic waves;

    Sammanfattning : This thesis compiles results of research in two mutuallydependent parts: 1) development of ferromagnetic resonance(FMR) spectrometer to study microwave properties offerromagnetic materials, and 2) characterization of new irongarnets: pulsed laser deposited Y3Fe5O12and Bi3Fe5O12films and Ce:Y3Fe5O12single crystal.First part describes a novelBroadbandFMRSpectrometerdesigned to characterize thin ferromagneticfilms.
