Blood Speckle-Tracking Based on High–Frame Rate Ultrasound Imaging in Pediatric Cardiology
Nyrnes, Siri Ann; Fadnes, Solveig; Wigen, Morten Smedsrud; Mertens, Luc; Løvstakken, Lasse (Peer reviewed; Journal article, 2020)Background: Flow properties play an important role in cardiac function, remodeling, and morphogenesis but cannot be displayed in detail with today’s echocardiographic techniques. The authors hypothesized that blood ... -
Effect of Ultrafast Imaging on Shear Wave Visualization and Characterization: An Experimental and Computational Study in a Pediatric Ventricular Model
Caenen, Annette; Pernot, Mathieu; Ekroll, Ingvild Kinn; Shcherbakova, Darya; Mertens, Luc; Swillens, Abigail Emily; Segers, Patrick (Journal article; Peer reviewed, 2017)Plane wave imaging in Shear Wave Elastography (SWE) captures shear wave propagation in real-time at ultrafast frame rates. To assess the capability of this technique in accurately visualizing the underlying shear wave ... -
Pulmonary Hypertension in Children is associated with Abnormal Flow patterns in the Main Pulmonary Artery as demonstrated by Blood Speckle Tracking
Mawad, Wadi; Fadnes, Solveig; Løvstakken, Lasse; Henry, Matthew; Mertens, Luc; Nyrnes, Siri Ann (Journal article; Peer reviewed, 2022)Background Paediatric pulmonary arterial hypertension (PAH) is characterized by increased pulmonary vascular resistance resulting in increased pulmonary artery (PA) and right ventricular pressure (RV). This is associated ... -
Right Ventricular Flow Dynamics in Dilated Right Ventricles: Energy Loss Estimation Based on Blood Speckle Tracking Echocardiography-A Pilot Study in Children
Mawad, Wadi; Løvstakken, Lasse; Fadnes, Solveig; Grønli, Thomas; Segers, Patrick; Mertens, Luc; Nyrnes, Siri Ann (Peer reviewed; Journal article, 2021)Using blood speckle tracking (BST) based on high-frame-rate echocardiography (HFRE), we compared right ventricle (RV) flow dynamics in children with atrial septal defects (ASDs) and repaired tetralogy of Fallot (rTOF). ...
