  1. 1. Development and evaluation of non-invasive ultrasonic methods for arterial characterization

    University dissertation from Department of Electrical Measurements, Lund University

    Author : Anders Eriksson; Lunds universitet.; Lund University.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; TDI; Tissue Doppler imaging; Arterial characterization; Non-invasive; Flow generation; PWV; Pulse wave velocity; Mät- och instrumenteringsteknik; Ultrasound; Vascular impedance;

    Abstract : As cardiovascular diseases have been the most common cause of mortality in the western world for decades, the demand for appropriate diagnostic methods is obvious. To facilitate the examination non-invasive methods are preferable since they do not require sensors within the circulation system. READ MORE

  2. 2. On the Use of Ultrasound Phase Data for Arterial Characterization

    University dissertation from Department of Biomedical Engineering, Lund university

    Author : Tobias Erlöv; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atherosclerosis; Ultrasound; Carotid Artery; Plaque Characterization; Scatter Size; Longitudinal Movement; Intima-Media Thickness;

    Abstract : Popular Abstract in Swedish Hjärt- och kärlsjukdomar som till exempel åderförkalkning utgör en av världens vanligaste dödsorsaker. I den här avhandlingen har vi utvecklat olika metoder som med hjälp av bildanalys ger värdefull information om kärlväggen i syfte att förbättra kunskapen om artärer och framförallt åderförkalkning.

  3. 3. Characterization of [18F]flutemetamol binding properties A β-amyloid PET imaging ligand

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Kerstin Heurling; Uppsala universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography PET ; molecular imaging; amyloid; tracer validation; Radiology; Radiologi;

    Abstract : The criteria for diagnosing Alzheimer’s disease (AD) have recently been revised to include the use of biomarkers for the in vivo presence of β-amyloid, one of the neuropathological hallmarks of AD. Examples of such biomarkers are positron emission tomography (PET) β-amyloid specific ligands, including [18F]flutemetamol. READ MORE

  4. 4. Ultrasonic Methods for Quantitative Carotid Plaque Characterization

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Erik Widman; KTH.; Karolinska Institutet.; Karolinska Institutet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicinsk teknologi; Medical Technology; Atherosclerosis; Cardiovascular Disease; Carotid Artery; Elasticity; ex vivo; in vivo; Phantom; Plaque; Polyvinyl Alcohol; Pulse Wave Imaging; Shear Wave Elastography; Speckle Tracking; Stroke; Ultrasound;

    Abstract : Cardiovascular diseases are the leading causes of death worldwide and improved diagnostic methods are needed for early intervention and to select the most suitable treatment for patients. Currently, carotid artery plaque vulnerability is typically determined by visually assessing ultrasound B-mode images, which is influenced by user-subjectivity. READ MORE

  5. 5. Characterization of the BOLD signal in functional MRI

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Author : Tomas Jonsson; Karolinska Institutet.; Karolinska Institutet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : In the last two decades, functional magnetic resonance imaging (fMRI) has become an important and widely used imaging technique for functional brain mapping. However, blood oxygen level dependent (BOLD) technique is quite insensitive and task invoked BOLD signal change at 3T is typically in the order of a few percent. READ MORE
