• A Methodical Quantification of Needle Visibility and Echogenicity in Ultrasound Images 

      Van De Berg, Nick J; Sanchez-Margallo, Juan A.; van Dijke, Arjan P; Langø, Thomas; Van Den Dobbelsteen, John J (Journal article; Peer reviewed, 2019)
      During ultrasound-guided percutaneous interventions, needle localization can be a challenge. To increase needle visibility, enhancements of both the imaging methods and the needle surface properties have been investigated. ...
    • Effect of ultrasound on the vasculature and extravasation of nanoscale particles imaged in real time 

      Yemane, Petros Tesfamichael; Åslund, Andreas K. O.; Snipstad, Sofie; Bjørkøy, Astrid; Grendstad, Kristin; Berg, Sigrid; Mørch, Ýrr Asbjørg; Torp, Sverre Helge; Hansen, Rune; Davies, Catharina de Lange (Journal article; Peer reviewed, 2019)
      Ultrasound and microbubbles have been found to improve the delivery of drugs and nanoparticles to tumor tissue. To obtain new knowledge on the influence of vascular parameters on extravasation and to elucidate the effect ...
    • Real-time Standard View Classification in Transthoracic Echocardiography using Convolutional Neural Networks 

      Østvik, Andreas; Smistad, Erik; Aase, Svein Arne; Haugen, Bjørn Olav; Løvstakken, Lasse (Journal article; Peer reviewed, 2018)
      Transthoracic echocardiography examinations are usually performed according to a protocol comprising different probe postures providing standard views of the heart. These are used as a basis when assessing cardiac function, ...
    • Sonopermeation Enhances Uptake and Therapeutic Effect of Free and Encapsulated Cabazitaxel 

      Snipstad, Sofie; Mørch, Ýrr; Sulheim, Einar; Åslund, Andreas; Pedersen, André; Hansen, Rune; Davies, Catharina de Lange; Berg, Sigrid (Peer reviewed; Journal article, 2021)
      Delivery of drugs and nanomedicines to tumors is often heterogeneous and insufficient and, thus, of limited efficacy. Microbubbles in combination with ultrasound have been found to improve delivery to tumors, enhancing ...
    • Ultrasound Improves the Delivery and Therapeutic Effect of Nanoparticle-Stabilized Microbubbles in Breast Cancer Xenografts 

      Snipstad, Sofie; Berg, Sigrid; Mørch, Ýrr Asbjørg; Bjørkøy, Astrid; Sulheim, Einar; Hansen, Rune; Grimstad, Ingeborg; van Wamel, Annemieke; Maaland, Astri Fjelde; Torp, Sverre Helge; Davies, Ruth Catharina de Lange (Peer reviewed; Journal article, 2017)
      Compared with conventional chemotherapy, encapsulation of drugs in nanoparticles can improve efficacy and reduce toxicity. However, delivery of nanoparticles is often insufficient and heterogeneous because of various ...
    • Ultrasound-Mediated Delivery of Chemotherapy into the Transgenic Adenocarcinoma of the Mouse Prostate Model 

      Fagerland, Stein-Martin Tilrum; Berg, Sigrid; Hill, Deborah Katherine; Snipstad, Sofie; Sulheim, Einar; Hyldbakk, Astrid; Kim, Jana; Davies, Catharina de Lange (Peer reviewed; Journal article, 2020)
      Ultrasound (US) in combination with microbubbles (MB) has had promising results in improving delivery of chemotherapeutic agents. However, most studies are done in immunodeficient mice with xenografted tumors. We used two ...
