  1. 1. Echocardiography/Doppler for the evaluation of coronary artery function, left ventricular function and the relationship between early diastolic and systolic function

    Författare :Reidar Winter; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary flow reserve; contrast echocardiography; early diastolic downward velocity; flow propagation velocity; colour M-mode; diastolic function; Echocardiography; Doppler; Kardiovaskulära systemet; Cardiovascular system;

    Sammanfattning : Two specific areas of development in echocardiography are assessment of left ventricular (LV) diastolic function and myocardial ischemia. This thesis describes echocardiographic methodology in these two areas. LÄS MER

  3. 2. Toward increased applicability of ultrasound contrast agents

    Författare :Malin Larsson; Lars-Åke Brodin; Anna Bjällmark; Kenneth Caidahl; Jan Engvall; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contrast agent; Contrast-to-tissue-ratio; Echocardiography; Endocardial border; Microbubbles; Multimodal; Phantom; Polymer; Ultrasound; Wall motion score index.; Teknik och hälsa; Technology and Health;

    Sammanfattning : Ultrasound is one of the most widely used modalities in medical imaging because of its high cost-effectiveness, wide availability in hospitals, generation of real-time images, and use of nonionizing radiation. However, the image quality can be insufficient in some patients. LÄS MER

  4. 3. Detection of Myocardial Ischemia using Real-Time Myocardial Contrast Echocardiography

    Författare :Petri Gudmundsson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial contrast echocardiography; MCE; stress echocardiography; adenosine; perfusion; real-time; visual; quantative; wall motion; power modulation; bedside; SPECT; coronary insufficiency;

    Sammanfattning : Diagnostisering av syrebrist i hjärtmuskeln med hjälp av kontrastförstärkt ultraljudsundersökning av hjärtmuskelns genomblödning. Ultraljudsundersökning av hjärtat (ekokardiografi) används mycket inom hjärtsjukvården idag, oftast för att utreda hjärtats och hjärtklaffarnas anatomi och funktion. LÄS MER

  7. 5. On Nonlinear Acoustics in Contrast Echocardiography

    Författare :Marcus Ressner; Birgitta Janerot-Sjöberg; Per Ask; Tomas Jansson; Hans Torp; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Ultrasound is one of the most commonly used noninvasive medical imaging techniques. Ultrasound contrast agents (UCA), consisting of encapsulated gas-filled microbubbles, have shown to increase the diagnostic precision in selected low echogenic patients. LÄS MER
