1. 1. 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

3. 2. The Utility of Ultrasmall Superparamagnetic Iron Oxide Contrast Agents for Cardiovascular Magnetic Resonance Imaging

   Författare :Lars Johansson; Håkan Ahlström; Hans-Jørgen Smith; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Magnetic resonance imaging; Contrast agent; Iron Oxide; Cardiovascular; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Sammanfattning : The purpose of this thesis was to investigate the utility of the Ultrasmall Superparamagnetic Iron Oxide Particle (USPIO), NC100150 Injection for assessment of macro- and microvascular morphology and function using magnetic resonance imaging. The feasibility of NC100150 Injection was tested for the following applications: Coronary angiography, Thrombus detection, Cardiac function, Myocardial perfusion, Assessment of myocardial blood volume and water exchange and finally assessment of endothelial integrity of the myocardium.

4. 3. Assessment of myocardial viability using magnetic resonance imaging

   Författare :Robert Jablonowski; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; myocardial infarction; hypertrophic cardiomyopathy; fibrosis; viability;

   Sammanfattning : Myocardial infarction (MI) following an acute coronary occlusion is a leading cause of morbidity and mortality. During revascularization, microemboli may complicate treatment and affect cardiac function. The long-term effects of microembolization are not fully elucidated. LÄS MER

5. 4. Cardiovascular fluid dynamics : methods for flow and pressure field analysis from magnetic resonance imaging

   Författare :Tino Ebbers; Håkan Arheden; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Cardiovascular blood flow is highly complex and incompletely understood. Blood flow patterns are expected to influence the opening and closing of normal and prosthetic heart valves, the efficiency of cardiac filling and ejection, and the resistance to thrombus formation within the heart.

7. 5. Preeclampsia and the Brain : Epidemiological and Magnetic Resonance Studies

   Författare :Maria Nelander; Johan Wikström; Anna-Karin Wikström; Inger Sundström Poromaa; Gerda Zeeman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preeclampsia; eclampsia; seizure; MRI; MRS; IVIM; dementia; cardiovascular disease; magnesium; cerebral organic osmolytes; perfusion; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Sammanfattning : Preeclampsia is a pregnancy specific syndrome that causes substantial maternal and fetal morbidity and mortality. One major contributor to maternal deaths is eclampsia, i.e. when seizures arise in the context of preeclampsia. LÄS MER
