L-DOPA-Coated Manganese Oxide Nanoparticles as Dual MRI Contrast Agents and Drug-Delivery Vehicles
(Journal article; Peer reviewed, 2016)Manganese oxide nanoparticles (MONPs) are capable of time-dependent magnetic resonance imaging contrast switching as well as releasing a surface-bound drug. MONPs give T2/T2* contrast, but dissolve and release T1-active ... -
Label-set impact on deep learning-based prostate segmentation on MRI
(Peer reviewed; Journal article, 2023)Background Prostate segmentation is an essential step in computer-aided detection and diagnosis systems for prostate cancer. Deep learning (DL)-based methods provide good performance for prostate gland and zones ... -
Labeling nanoparticles: Dye leakage and altered cellular uptake
(Journal article, 2016)In vitro and in vivo behavior of nanoparticles (NPs) is often studied by tracing the NPs with fluorescent dyes. This requires stable incorporation of dyes within the NPs, as dye leakage may give a wrong interpretation of ... -
Labelling of olfactory ensheathing cells with micron-sized particles of iron oxide and detection by MRI
(Journal article; Peer reviewed, 2012)A crucial issue in transplant‐mediated repair of the damaged central nervous system (CNS) is serial non‐invasive imaging of the transplanted cells, which has led to interest in the application of magnetic resonance imaging ... -
Laboratory experiments on ultrasonic logging through casing for barrier integrity validation
(Chapter, 2017)Verification of annular barriers is essential for well integrity, with ultrasonic methods being central in well integrity testing for many decades. By doing ultrasonic pitch-catch measurements on a bench top laboratory ... -
Lack of transfer of skills after virtual reality simulator training with haptic feedback
(Journal article; Peer reviewed, 2017)Background and objective: Virtual reality (VR) simulators enrich surgical training and offer training possibilities outside of the operating room (OR). In this study, we created a criterion-based training program on a VR ... -
Large inter-individual differences in responses to a block of high intensity aerobic interval training: A case series in national-level cyclists and triathletes
(Journal article; Peer reviewed, 2020)The aim was to investigate individual responses on VO2maxand performance to a block of high intensity aerobic interval training (HIIT) in national-level endurance athletes. METHODS: National-level cyclists and triathletes ... -
Large scale plasma proteomics identifies novel proteins and protein networks associated with heart failure development
(Peer reviewed; Journal article, 2024)Heart failure (HF) causes substantial morbidity and mortality but its pathobiology is incompletely understood. The proteome is a promising intermediate phenotype for discovery of novel mechanisms. We measured 4877 plasma ... -
Left Atrial Volume, Cardiorespiratory Fitness, and Diastolic Function in Healthy Individuals: The HUNT Study, Norwa
(Journal article; Peer reviewed, 2020)Background Left atrial (LA) size and cardiorespiratory fitness (CRF) are predictors of future cardiovascular events in high‐risk populations. LA dilatation is a diagnostic criterion for left ventricular diastolic ... -
Left ventricular diastolic dysfunction predicts mortality in patients with systemic sclerosis
(Journal article; Peer reviewed, 2018)Background Primary cardiac affection is common and is a major cause of death in systemic sclerosis (SSc), but there are knowledge gaps regarding the effect of cardiac dysfunction on mortality. Objectives The purpose ... -
Left ventricular global strains by linear measurements in three dimensions: interrelations and relations to age, gender and body size in the HUNT Study
(Journal article; Peer reviewed, 2019)Strain is a relative deformation and has three dimensions, in the left ventricle (LV) usually longitudinal (εL), transmural (εT) and circumferential (εC) strain. All three components can be measured generically by the basic ... -
Left ventricular longitudinal shortening: relation to stroke volume and ejection fraction in ageing, blood pressure, body size and gender in the HUNT3 study
(Peer reviewed; Journal article, 2020)Background: Aims of this cross-sectional study were to assess: the relative contribution of left ventricular (LV) systolic long-axis shortening (mean mitral annular plane systolic excursion, MAPSE) to stroke volume (SV), ... -

Left Ventricular Systolic Function in Long-Term Survivors of Allogeneic Hematopoietic Stem Cell Transplantation
(Peer reviewed; Journal article, 2020)Background Allogeneic hematopoietic stem cell transplantation (allo-HSCT), a potentially curative therapy for malignant and nonmalignant diseases, is being increasingly used in younger patients. Although allo-HSCT survivors ... -
Left-Ventricular Volume Estimation in Contrast-Enhanced Echocardiography Using Deep Learning
(Chapter, 2023)Accurate estimation of left ventricular (LV) volume is important for the diagnosis and management of cardiac disease. Contrast-enhanced ultrasound (CEUS) helps improve the visualization of the endocardial borders and is ... -
