Acute and potentially persistent effects of scuba diving on the blood transcriptome of experienced divers
Eftedal, Ingrid; Ljubkovic, Marko; Flatberg, Arnar; Jørgensen, Arve; Brubakk, Alf O; Dujic, Zeljko (Journal article; Peer reviewed, 2013)During scuba diving, the circulatory system is stressed by an elevated partial pressure of oxygen while the diver is submerged and by decompression-induced gas bubbles on ascent to the surface. This diving-induced stress ... -
Animal study assessing safety of an acoustic coupling fluid that holds the potential to avoid surgically induced artifacts in 3D ultrasound guided operations
Jakola, Asgeir S; Jørgensen, Arve; Selbekk, Tormod; Michler, Ralf-Peter; Solheim, Ole; Torp, Sverre Helge; Sagberg, Lisa Millgård; Aadahl, Petter; Unsgård, Geirmund (Journal article; Peer reviewed, 2014)Background Use of ultrasound in brain tumor surgery is common. The difference in attenuation between brain and isotonic saline may cause artifacts that degrade the ultrasound images, potentially affecting resection grades ... -
Deep learning versus iterative image reconstruction algorithm affects depiction of coronary vessels and calcified plaques in CCTA
Ofstad, Anders (Master thesis, 2024)Bakgrunn Koronar hjertesykdom fremstilles ikke-invasivt ved bruk av koronar CT angiografi. Gullstandard for å lage CT-bilder er iterative rekonstruksjons-metoder (IR-metoder). Ny teknologi gjør det nå mulig å lage CT-bilder ... -
Deteksjon og karakterisering av lymfeknuter ved lungekreft: En pilotstudie
Haugdal, Dina (Bachelor thesis, 2019)Lungekreft er i dag den enkeltstående kreftformen som tar livet av flest mennesker i Norge. Årsaken til at så få overlever er at lungekreft oppdages sent og det er lite kunnskap om maligne lymfeknuter i lungehilii og ... -
Eccentric exercise 48 h prior to simulated diving has no effect on vascular bubble formation in rats
Jørgensen, Arve; Ekdahl, Anna Madeleine; Havnes, Marianne Bjordal; Eftedal, Ingrid (Journal article; Peer reviewed, 2014)PURPOSE: Decompression sickness (DCS) caused by vascular bubble formation is a major risk when diving. Prior studies have shown that physical exercise has a significant impact in both reducing and increasing bubble formation. ... -
Effects of hyperbaric oxygen preconditioning on cardiac stress markers after simulated diving.
Jørgensen, Arve; Foster, Philip P; Brubakk, Alf O; Eftedal, Ingrid (Journal article; Peer reviewed, 2013)Hyperbaric oxygen preconditioning (HBO-PC) can protect the heart from injury during subsequent ischemia. The presence of high loads of venous gas emboli (VGE) induced by a rapid ambient pressure reduction on ascent from ... -
Feildosering av metotreksat
Husby, Maren Wennberg; Bjørnsen, Lars Petter Bache-Wiig; Jørgensen, Arve; Lassen, Tone Merete; Jacobsen, Dag; Laugsand, Lars Erik (Peer reviewed; Journal article, 2024)En eldre kvinne ble henvist til akuttmottaket på grunn av økende tungpustethet de siste tre ukene. Feiladministrering av metotreksat var årsaken til plagene. -
Fluoroscopy-free resuscitative endovascular balloon occlusion of the aorta (REBOA) for controlling life threatening postpartum hemorrhage
STENSÆTH, KNUT HAAKON; SØVIK, EDMUND; HAIG, YLVA; Skomedal, Erna; Jørgensen, Arve (Journal article; Peer reviewed, 2017)Background Severe postpartum hemorrhage occurs in 1/1000 women giving birth. This condition is often dramatic and may be life threatening. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) has in recent ... -
Impact of baseline coronary flow and its distribution on Fractional Flow Reserve prediction
Muller, Lucas Omar; Fossan, Fredrik Eikeland; Bråten, Anders Tjellaug; Jørgensen, Arve; Wiseth, Rune; Hellevik, Leif Rune (Journal article; Peer reviewed, 2019)Model‐based prediction of fractional flow reserve (FFR) in the context of stable coronary artery disease (CAD) diagnosis requires a number of modelling assumptions. One of these assumptions is the definition of a baseline ... -
Machine learning augmented reduced-order models for FFR-prediction
Fossan, Fredrik Eikeland; Müller, Lucas O.; Sturdy, Jacob; Bråten, Anders Tjellaug; Jørgensen, Arve; Wiseth, Rune; Hellevik, Leif Rune (Peer reviewed; Journal article, 2021)Computational predictions in cardiovascular medicine have largely relied on explicit models derived from physical and physiological principles. Recently, the application of artificial intelligence in cardiovascular medicine ... -
Uncertainty quantification and sensitivity analysis for computational FFR estimation in stable coronary artery disease
Fossan, Fredrik Eikeland; Sturdy, Jacob; Muller, Lucas Omar; Strand, Andreas; Bråten, Anders Tjellaug; Jørgensen, Arve; Wiseth, Rune; Hellevik, Leif Rune (Journal article; Peer reviewed, 2018)Purpose The main objectives of this study are to validate a reduced-order model for the estimation of the fractional flow reserve (FFR) index based on blood flow simulations that incorporate clinical imaging and ...
