A randomized study of the effect of patient positioning on setup reproducibility and dose distribution to organs at risk in radiotherapy of rectal cancer patients
(Peer reviewed; Journal article, 2015)Background:The patient positioning in pelvic radiotherapy (RT) should be decided based on both reproducibilityand on which position that yields the lowest radiation dose to the organs at risk (OAR), and thereby less ... -
Randomized Trial of Interleukin-6 Receptor Inhibition in Patients With Acute ST-Segment Elevation Myocardial Infarction
(Journal article; Peer reviewed, 2021)Background - Prompt myocardial revascularization with percutaneous coronary intervention (PCI) reduces infarct size and improves outcomes in patients with ST-segment elevation myocardial infarction (STEMI). However, as ... -
Rapid declines in systolic blood pressure are associated with an increase in pulse transit time
(Peer reviewed; Journal article, 2020)Background The correlation between pulse transit time and blood pressure has been proposed as a route to measure continuous non-invasive blood pressure. We investigated whether pulse transit time trends could model blood ... -
Rapportering av mistanke om barnemishandling - en kartleggingsstudie blant radiografer
(Bachelor thesis, 2021)Temaet for oppgaven er barnemishandling, hvor formålet med studien er å se på hvordan yrkeserfaring og grad av opplæring hos radiografer har en sammenheng med rapporteringsvaner. Vi vil også kartlegge kunnskapen til de ... -
Rationale and design of the PRevention of cArdiac Dysfunction during Adjuvant breast cancer therapy (PRADA II) trial: a randomized, placebo-controlled, multicenter trial
(Journal article, 2021)Background Recent advances in the treatment algorithms of early breast cancer have markedly improved overall survival. However, anthracycline- and trastuzumab-associated cardiotoxicity may lead to dose-reduction or halt ... -
Rationale for the ASSAIL-MI-trial: a randomised controlled trial designed to assess the effect of tocilizumab on myocardial salvage in patients with acute ST-elevation myocardial infarction (STEMI).
(Journal article; Peer reviewed, 2019)Introduction Interleukin-6 (IL-6) may be involved in ischaemia-reperfusion injury and myocardial remodelling after myocardial infarction (MI). We have recently shown that IL-6 inhibition by tocilizumab attenuates systemic ... -
Real-time 3-D echocardiography:challenges of parallel transmission and acquisition
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:104, Doctoral thesis, 2014)Ultrasound imaging is a well-established, noninvasive and relatively low cost method for assessing the cardiac function. By providing dense image volumes in real-time, three-dimensional echocardiography could improve and ... -
Real-time 3D left ventricle segmentation and ejection fraction using deep learning
(Peer reviewed; Journal article, 2021)Supervised learning for 3D left ventricle (LV) ultrasound segmentation is difficult due to the challenges of acquiring large amounts annotated data. In this work, pre-training on a weakly labeled dataset, combined with ... -
Real-Time Automatic Ejection Fraction and Foreshortening Detection Using Deep Learning
(Peer reviewed; Journal article, 2020)Volume and ejection fraction (EF) measurements of the left ventricle (LV) in 2-D echocardiography are associated with a high uncertainty not only due to interobserver variability of the manual measurement, but also due to ... -
Real-time automatic quantification of left ventricular function by hand-held ultrasound devices in patients with suspected heart failure: a feasibility study of a diagnostic test with data from general practitioners, nurses and cardiologists
(Peer reviewed; Journal article, 2022)Objectives To evaluate the feasibility and reliability of hand-held ultrasound (HUD) examinations with real-time automatic decision-making software for ejection fraction (autoEF) and mitral annular plane systolic excursion ... -
Real-Time Echocardiography Guidance for Optimized Apical Standard Views
(Journal article; Peer reviewed, 2022) -
Real-time forecasting of emergency department arrivals using prehospital data
(Journal article; Peer reviewed, 2019)Background: Crowding in emergency departments (EDs) is a challenge globally. To counteract crowding in day-to-day operations, better tools to improve monitoring of the patient flow in the ED is needed. The objective of ... -
Real-time segmentation of blood vessels, nerves and bone in ultrasound-guided regional anesthesia using deep learning
(Peer reviewed; Journal article, 2021)Images from ultrasound-guided regional anesthesia procedures can be difficult to interpret, especially by non-experts. In this work, deep convolutional neural networks were used to segment blood vessels, nerves and bone ... -
Real-time Standard View Classification in Transthoracic Echocardiography using Convolutional Neural Networks
(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, ... -
Real-time temporal coherent left ventricle segmentation using convolutional LSTMs

Reasons for prolonged time for diagnostic workup for stage I-II lung cancer and estimated effect of applying an optimized pathway for diagnostic procedures
(Journal article; Peer reviewed, 2019)Background:Minimizing the time until start of cancer treatment is a political goal. In Norway, the target time forlung cancer is 42 days. The aim of this study was to identify reasons for delays and estimate the effect on ... -
REBOARREST, resuscitative endovascular balloon occlusion of the aorta in non-traumatic out-of-hospital cardiac arrest: a study protocol for a randomised, parallel group, clinical multicentre trial
(Journal article; Peer reviewed, 2021)Background: Survival after out-of-hospital cardiac arrest (OHCA) is poor and dependent on high-quality cardiopulmonary resuscitation. Resuscitative endovascular balloon occlusion of the aorta (REBOA) may be advantageous ... -
Recovery trajectories in common musculoskeletal complaints by diagnosis contra prognostic phenotypes
(Peer reviewed; Journal article, 2021)Background There are large variations in symptoms and prognostic factors among patients sharing the same musculoskeletal (MSK) diagnosis, making traditional diagnostic labelling not very helpful in informing treatment ... -
