  1. 1. Aspects on wall properties of the brachial artery in man with special reference to SLE and insulin-dependent diabetes mellitus

    Detta är en avhandling från Institutionen för medicin och hälsa

    Författare :Niclas Bjarnegård; Toste Länne; Reinhard Volkmann; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arterial wall; atherosclerotic; brachial artery BA ; type 1 diabetes; ulse wave velocity PWV ; pulse wave analysis PWA ; intima-media thickness IMT ; nitrate mediated dilatation NMD ; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Diabetology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Diabetologi;

    Sammanfattning : The mechanical properties of the arterial wall are of great importance for blood pressure regulation and cardiac load. With increasing age, large arteries are affected by increased wall stiffness. LÄS MER

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

    Detta är en avhandling från Department of Electrical Measurements, Lund University

    Författare :Anders Eriksson; [1999]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 3. Ultrasonic Methods for Quantitative Carotid Plaque Characterization

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Erik Widman; Matilda Larsson; Mark L. Palmeri; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND 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; Medicinsk teknologi; Medical Technology;

    Sammanfattning : 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. LÄS MER

  4. 4. Ultrasonic Methods for 2D Arterial Wall Movement Measurements

    Detta är en avhandling från Magnus Cinthio, Department of Electrical Measurements, LTH, Box 118, 221 00 Lund, Sweden

    Författare :Magnus Cinthio; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue Doppler imaging; Cardiovascular system; Diagnostik; Diagnostics; Kardiovaskulära systemet; arteries; ultrasound; shear stress; axial movement; radial movement; Arterial distension; Arterial lumen diameter; PWV; Arterial longitudinal movement; pulse-wave velocity;

    Sammanfattning : Cardiovascular diseases constitute the major cause of morbidity and mortality in the Western World. To increase our knowledge of cardiovascular diseases, it is important to find methods, preferably non-invasive ones, to study very early manifestations of vascular disease. LÄS MER

  5. 5. Measurements in Idiopathic Normal Pressure Hydrocephalus Computerized neuropsychological test battery and intracranial pulse waves

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Anders Behrens; Jan Malm; Anders Eklund; Eva Elgh; Niklas Lenfeldt; Marianne Juhler; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hydrocephalus; Normal Pressure; Neuropsychological tests; Neuropsychology; Reliability and validity; Software; Dementia; intracranial pressure; spinal puncture; cerebrospinal fluid pressure; pulse pressure waves; Blood flow velocity; Middle cerebral artery; Pulsatility index; neurologi; Neurology;

    Sammanfattning : Idiopathic Normal Pressure Hydrocephalus (INPH) is a condition affecting gait, cognition and continence. Radiological examination reveals enlarged ventricles of the brain. A shunt that drains CSF from the ventricles to the abdomen often improves the symptoms. LÄS MER
