    Sammanfattning : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.

    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.

  4. 13. Prenatal Tisse Velocity Imaging of the Heart : A new approach to assess fetal myocardial function

    Författare :Nina Elmstedt; Lars-Åke Brodin; Britta Lind; Karel Marsal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The general aim of this thesis has been to evaluate color‐coded tissue velocity imaging (TVI) as an approach to developing a new, non‐invasive assessment method for fetal myocardial function. Such a method could hypothetically give early indications of fetal pathology, as myocardial dysfunction is often the consequence when the circulation tries to adapt to deteriorating situations.

  5. 14. Ultrasonic Quantification of Skeletal Muscle Dynamics : Feasibility and Limitations

    Författare :Frida Lindberg; Lars-Åke Brodin; Christer Grönlund; Tomas Jansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrasound; skeletal muscle; intramuscular; dynamics; Tissue Doppler Imaging; Speckle Tracking; strain; quantification;

    Sammanfattning : Pain and disorders of the human skeletal muscles are one of the most common reasons for medical consultations in the western countries today and there is a great need to improve both the understanding and treatment of several different muscular conditions.Techniques describing the muscle function in vivo are often limited by either their invasiveness or lack of spatial resolution.

    Sammanfattning : Since 2008 advanced home healthcare agencies (ASiH) in a larger Swedish county council has underwent a transformation, to become part of a coming concept: networked healthcare (NVS). NVS means that intermediate multi-organizational healthcare (IMV) will be produced often in the home, and from 2013 to an increasing number of patients in different age groups with different diagnoses and medical conditions - in large variability of needs.
