    • Effect of Temporal and Spatial Smoothing on Speckle–Tracking‑Derived Strain in Neonates 

      Khan, Muhammad Umael; Omdal, Tom Roar; Greve, Gottfried; Grong, Ketil; Matre, Knut (Journal article; Peer reviewed, 2021)
      Clinical application of strain in neonates requires an understanding of which image acquisition and processing parameters affect strain values. Previous studies have examined frame rate, transmitting frequency, and vendor ...

    • The influence of region of interest width in fetal 2D-speckle tracking echocardiography late in pregnancy 

      Omdal, Tom Roar; Khan, Muhammad Umael; Ebbing, Cathrine; Kessler, Jörg; Karlsen, Henriette Odland; Leirgul, Elisabeth; Matre, Knut; Greve, Gottfried (Journal article; Peer reviewed, 2021)
      Speckle tracking echocardiography is a promising method for assessment of myocardial function in fetal and neonatal hearts, but further studies are necessary to validate and optimize the settings for use in fetal cardiology. ...

    • Speckle tracking derived strain in neonates: planes, layers and drift 

      Khan, Muhammad Umael; Omdal, Tom R.; Matre, Knut; Greve, Gottfried (Journal article; Peer reviewed, 2021)
      The aims of this study was to assess the effect of using a four chamber versus a three plane model on speckle tracking derived global longitudinal strain, the effects of drift compensation, the effect of assessing strain ...
