Data acquisition for high resolution blood oxygen level dependent fMRI
(Doctoral theses at NTNU;2018:75, Doctoral thesis, 2018)Blood oxygen level dependent functional magnetic resonance imaging (BOLD fMRI) is an important non-invasive technique for investigation of brain function. Using BOLD fMRI, brain activity can be localized with high spatial ... -
Data Adaptive 2-D Tracking Doppler for High-Resolution Spectral Estimation
(Peer reviewed; Journal article, 2019)Spectral broadening in pulsed-wave Doppler caused by the transit-time effect deteriorates the frequency resolution and may cause overestimation of maximum velocities in high-velocity blood flow regions and for large ... -
Deadly diving? Physiological and behavioural management of decompression stress in diving mammals
(Journal article; Peer reviewed, 2012)Decompression sickness (DCS; ‘the bends’) is a disease associated with gas uptake at pressure. The basic pathology and cause are relatively well known to human divers. Breath-hold diving marine mammals were thought to be ... -
Decidual and placental NOD1 is associated with inflammation in normal and preeclamptic pregnancies
(Peer reviewed; Journal article, 2021)Introduction: Inflammation is a normal physiological process that increases to harmful levels in preeclampsia. It affects the interaction between maternal immune cells and fetal trophoblasts at both sites of the maternal-fetal ... -
Defining the cut-off point of clinically significant postoperative fatigue in three common fatigue scales
(Journal article; Peer reviewed, 2018)Purpose Postoperative fatigue (POF) is an often underestimated problem after surgery. Studies on POF often report fatigue scores without relating this to the clinical relevance for the patients. The aim of this study was ... -
Deletion of Kinin B2 receptor alters muscle metabolism and exercise performance
(Journal article, 2015)Metabolic syndrome is a cluster of metabolic risk factors such as obesity, diabetes and cardiovascular diseases. Mitochondria is the main site of ATP production and its dysfunction leads to decreased oxidative phosphorylation, ... -
Demonstration of non-gaussian restricted diffusion in tumor cells using diffusion time-dependent diffusion-weighted magnetic resonance imaging contrast
(Peer reviewed; Journal article, 2016)The diffusion-weighted magnetic resonance imaging (DWI) technique enables quantification of water mobility for probing microstructural properties of biological tissue and has become an effective tool for collecting information ... -
Design of a study evaluating the effects, health economics, and stakeholder perspectives of a multi-component occupational rehabilitation program with an added workplace intervention - A study protocol
(Journal article; Peer reviewed, 2018)Background Recent research has suggested that interventions at the workplace might be the most potent ingredient in return to work interventions, but few studies have investigated the different effects of workplace ... -
Design, Fabrication and Testing Highly Sensitive Single Element Doppler Transducers
(Journal article; Peer reviewed, 2018)Three common piezoelectric materials have been studied for use in pulsed wave Doppler ultrasound, where high sensitivity is required, while bandwidth is less important. A large transducer aperture, 80 mm 2 , results in a ... -
"Det er ikke bare å tømme bøtta rett ut." En kvalitativ studie av bioingeniørers erfaringer med praksisveiledning av studenter i medisinske laboratorier.
(Master thesis, 2020)Bakgrunn: Bioingeniører er autoriserte helsepersonell, og de fleste arbeider i medisinske laboratorier ved sykehus. I løpet av studiet har alle bioingeniørstudentene praksis i medisinske laboratorier hvor de veiledes av ... -
Detailed flow visualization in fetal and neonatal hearts using 2-D speckle tracking
(Journal article, 2016)Two-dimensional blood speckle tracking has shown promise for measuring the complex flow patterns in neonatal hearts when based on linear array and high-frame-rate plane wave imaging. For phased array pediatric imaging, ... -
Detection and differentiation of breast cancer sub-types using a cPLA2a activatable fluorophore
(Journal article; Peer reviewed, 2019)Cytosolic phospholipase A2α (cPLA2α) has been shown to be elevated in breast cancer and is a potential biomarker in the differentiation of molecular sub-types. Using a cPLA2α activatable fluorophore, DDAO arachidonate, we ... -
Detection of recurrent prostate cancer with 18F-Fluciclovine PET/MRI
(Peer reviewed; Journal article, 2020)Objective: Simultaneous PET/MRI combines soft-tissue contrast of MRI with high molecular sensitivity of PET in one session. The aim of this prospective study was to evaluate detection rates of recurrent prostate cancer by ... -
Deteksjon og karakterisering av lymfeknuter ved lungekreft: En pilotstudie
(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 ... -
