  1. 11. Quantitative assessment of myocardial infarction: On the relationship between anatomy and electrophysiology using MRI and ECG

    Författare :Henrik Engblom; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; magnetic resonance imaging; tomography; medical instrumentation; Clinical physics; radiology; electrocardiography; myocardial infarction; ischemic heart disease; Cardiovascular system; Diagnostics; Diagnostik; Kardiovaskulära systemet;

    Sammanfattning : Both presence and extent of myocardial infarction are important prognostic factors for mortality and quality of life in patients with ischemic heart disease. Thus, it is of great clinical importance to be able to diagnose and characterize myocardial infarction. LÄS MER

  3. 12. Dysfunctional but viable myocardium - ischemic heart disease assessed by magnetic resonance imaging and single photon emission computed tomography

    Författare :Martin Ugander; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; medical instrumentation; Klinisk fysiologi; radiology; tomography; Clinical physics; non-invasive imaging; myocardial infarction; viability; Physiology; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : The assessment of ischemic heart disease (IHD) often focuses on the detection of dysfunctional but viable myocardium which may improve in function following revascularization. Dysfunctional but viable myocardium is identified by distinct characteristics with regards to function, perfusion and viability. LÄS MER

  4. 13. Assessment of Atherosclerosis by Whole-Body Magnetic Resonance Angiography

    Författare :Tomas Hansen; Håkan Ahlström; Lars Lind; Johan Wikström; Lars Johansson; Björn Fagerberg; Uppsala universitet; []
    Nyckelord :Radiology; Atherosclerosis; Magnetic Resonance Angiography; Epidemiology; Radiologisk forskning;

    Sammanfattning : Atherosclerosis is a serious threat to public health and a major cause of morbidity and mortality. In this doctoral research, the feasibility of using whole-body magnetic resonance angiography (WBMRA) was studied as a principal aim both in patients and in an epidemiological setting. LÄS MER

  5. 14. Clinically Unrecognized Myocardial Scars Detected by MRI

    Författare :Raquel Espregueira Themudo; Tomas Bjerner; Andrew Arai; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; unrecognized myocardial scars; myocardial infarction; epidemiology; magnetic resonance; computed topographic coronary angiography; exercise test; NT-proBNP; Radiology; Radiologi; Cardiology; Kardiologi;

    Sammanfattning : A high percentage of unrecognized myocardial infarctions (UMIs) seen at delayed-enhanced magnetic resonance imaging (DE-MRI) are not detected by ECG. DE-MRI-detected UMIs are independent predictors of cardiovascular events in patients with coronary artery disease. LÄS MER

  7. 15. Non-invasive imaging for improved cardiovascular diagnostics : Shear wave elastography, relative pressure estimation, and tomographic reconstruction

    Författare :David Marlevi; Matilda Larsson; Reidar Winter; Massimiliano Colarieti-Tosti; Kathryn Nightingale; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical imaging; Cardiovascular disease; Atherosclerosis; Hemodynamics; Ultrasound; Shear Wave Elastography SWE ; Magnetic Resonance Imaging MRI ; 4D flow MRI; Relative Pressure; Virtual Work-Energy; micro-Computed Tomography micro-CT ; Tomographic reconstruction; Pre-clinical imaging; Medicinsk avbildning; Hjärt-kärlsjukdomar; Ateroskleros; Hemodynamik; Ultraljud; Skjuvvågselastografi SWE ; Magnetresonanstomografi MRI ; 4D flödes-MRI; Tryckfall; Virtuellt flöde; mikro-Datortomografi mikro-CT ; Tomografisk rekonstruktion; Preklinisk avbildning; Medicinsk teknologi; Medical Technology;

    Sammanfattning : Throughout the last century, medical imaging has come to revolutionise the way we diagnose disease, and is today an indispensable part of virtually any clinical practice. In cardiovascular care imaging is extensively utilised, and the development of novel techniques promises refined diagnostic abilities: ultrasound elastography allows for constitutive tissue assessment, 4D flow magnetic resonance imaging (MRI) enables full-field flow mapping, and micro-Computed Tomography (CT) permits high-resolution imaging at pre-clinical level.
