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 ... -
Increasing region of interest width reduces neonatal circumferential strain
Mørch, Johannes Kjartansson; Kolnes, Elisabeth Horne; Greve, Gottfried; Omdal, Tom Roar; Ebbing, Cathrine; Kessler, Jørg; Khan, Umael (Journal article; Peer reviewed, 2024)Objective There is growing interest in speckle tracking echocardiography-derived strain as a measure of left ventricular function in neonates. However, knowledge gaps remain regarding the effect of image acquisition and ... -
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. ... -
Myocardial function including estimates of myocardial work in young adults born very preterm or with extremely low birthweight - a cohort study
Engan, Britt; Omdal, Tom Roar; Greve, Gottfried; Vollsæter, Maria; Leirgul, Elisabeth (Journal article; Peer reviewed, 2023)Background Preterm birth and low birthweight have been associated with increased risk of heart failure and cardiovascular disease in young adulthood. However, results from clinical studies of myocardial function are not ... -
Systolic myocardial function measured by echocardiographic speckle-tracking and peak oxygen consumption in pediatric childhood cancer survivors—a PACCS study
Engan, Britt; Diab, Simone; Brun, Henrik; Raastad, Truls; Torsvik, Ingrid Kristin; Omdal, Tom Roar; Zamanzad Ghavidel, Fatemeh; Greve, Gottfried; Ruud, Ellen; Edvardsen, Elisabeth; Leirgul, Elisabeth (Journal article; Peer reviewed, 2023)Background: Cancer therapy-related cardiotoxicity is a major cause of cardiovascular morbidity in childhood cancer survivors. The aims of this study were to investigate systolic myocardial function and its association to ...
