      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 ...
    • Intravascular Targets for Molecular Contrast-Enhanced Ultrasound Imaging 

      Moestue, Siver Andreas; Gribbestad, Ingrid S; Hansen, Rune (Journal article; Peer reviewed, 2012)
      Molecular targeting of contrast agents for ultrasound imaging is emerging as a new medical imaging modality. It combines advances in ultrasound technology with principles of molecular imaging, thereby allowing non-invasive ...
    • Multimodal Phantom of Liver Tissue 

      Chmarra, Magdalena Karolina; Hansen, Rune; Mårvik, Ronald; Langø, Thomas (Journal article; Peer reviewed, 2013)
      Medical imaging plays an important role in patients' care and is continuously being used in managing health and disease. To obtain the maximum benefit from this rapidly developing technology, further research is needed. ...
    • Nanoparticle delivery to the brain - By focused ultrasound and self-assembled nanoparticle-stabilized microbubbles 

      Åslund, Andreas; Berg, Sigrid; Hak, Sjoerd; Mørch, Ýrr Asbjørg; Torp, Sverre Helge; Sandvig, Axel; Widerøe, Marius; Hansen, Rune; Davies, Ruth Catharina de Lange (Journal article, 2015)
      The blood–brain barrier (BBB) constitutes a significant obstacle for the delivery of drugs into the central nervous system (CNS). Nanoparticles have been able to partly overcome this obstacle and can thus improve drug ...
    • Nanoparticle-stabilized microbubbles for multimodal imaging and drug delivery 

      Mørch, Ýrr Asbjørg; Hansen, Rune; Berg, Sigrid; Åslund, Andreas; Glomm, Wilhelm; Eggen, Siv; Schmid, Ruth; Johnsen, Heidi; Kubowicz, Stephan; Snipstad, Sofie; Sulheim, Einar; Hak, Sjoerd; Singh, Gurvinder; McDonagh, Birgitte Hjelmeland; Blom, Hans; Davies, Ruth Catharina de Lange; Stenstad, Per Martin (Journal article, 2015)
      Microbubbles (MBs) are routinely used as contrast agents for ultrasound imaging. The use of ultrasound in combination with MBs has also attracted attention as a method to enhance drug delivery. We have developed a technology ...
    • Nanoparticle uptake by brain endothelial cells and focused ultrasound-mediated transport across the blood-brain barrier 

      Baghirov, Habib (Doctoral theses at NTNU;2017:3, Doctoral thesis, 2016)
      More and more people in the world suffer from various brain diseases such as Parkinson’s disease, Alzheimer’s disease and brain cancer. One of the reasons it is so difficult to treat them is the blood-brain barrier (BBB) ...
    • The Effect of Sonication on Extravasation and Distribution of Nanoparticles and Dextrans in Tumor Tissue Imaged by Multiphoton Microscopy 

      Yemane, Petros Tesfamichael; Åslund, Andreas; Sæterbø, Kristin Grendstad; Bjørkøy, Astrid; Snipstad, Sofie; van Wamel, Annemieke; Berg, Sigrid; Mørch, Ýrr Asbjørg; Hansen, Rune; Angelsen, Bjørn Atle Johan; Davies, Catharina de Lange (Journal article; Peer reviewed, 2018)
      Ultrasound (US)and systemic administration of microbubbles (MBs)have been shown to improve the delivery of drugs and nanoparticles (NPs)to tumor tissue. A better understanding of the mechanisms is crucial for effective ...
    • 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 (Journal article; Peer reviewed, 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 and distribution of polymeric nanoparticles in the normal brain parenchyma of a metastatic brain tumour model 

      Baghirov, Habib; Snipstad, Sofie; Sulheim, Einar; Berg, Sigrid; Hansen, Rune; Thorsen, Frits; Mørch, Ýrr Asbjørg; Davies, Catharina de Lange; Åslund, Andreas (Journal article; Peer reviewed, 2018)
      The treatment of brain diseases is hindered by the blood-brain barrier (BBB) preventing most drugs from entering the brain. Focused ultrasound (FUS) with microbubbles can open the BBB safely and reversibly. Systemic drug ...
