    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

  3. 2. Capturing the breath of the heart by magnetic resonance imaging : five-dimensional cardio-respiratory resolved cine imaging during free breathing

    Författare :Karen Holst; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cardiac imaging with cardiovascular magnetic resonance has the advantage of enabling dynamic visualizations, several quantifiable measures, and good soft-tissue contrast. However, a major drawback is the need for breath holding during many acquisitions to limit motion artifacts. LÄS MER
