Metal Artifact Reduction for Total Hip Replacement in MRI
(Master thesis, 2019)Projektets baggrund: Philips 1.5 T-scanneren gennemgik en hardware-og softwareopgradering. Under denne proces var nogle af protokollerne ikke blevet opgraderet. Den gyldne standard pseudotumor hofte protokol bestod af 4 ... -
MGMT Promoter Methylation Status Is Not Related to Histological or Radiological Features in IDH Wild-type Glioblastomas
(Peer reviewed; Journal article, 2020)O6-methylguanine DNA methyltransferase (MGMT) promoter methylation is an important favorable predictive marker in patients with glioblastoma (GBM). We hypothesized that MGMT status could be a surrogate marker of pretreatment ... -
MicroRNA as biomarkers in colorectal cancer
(Master thesis, 2016)Colorectal cancer (CRC) is one of the worlds leading causes of cancer-related deaths in both men and women. Nearly 1.4 million new cases were reported in 2012 and over half of the cases ended in death. High mortality rates ... -
Migraine and endothelial function: The HUNT3 Study.
(Journal article; Peer reviewed, 2016)Background: Reduced endothelial function is associated with elevated risk of cardiovascular disease, but evidence on the association between migraine and endothelial function is conflicting. The aim of this population-based ... -
Minimally invasive beat-by-beat monitoring of cardiac power in normal hearts and during acute ventricular dysfunction
(Journal article; Peer reviewed, 2016)Cardiac power, the product of aortic flow and blood pressure, appears to be a fundamental cardiovascular parameter. The simplified version named cardiac power output (CPO), calculated as the product of cardiac output (CO) ... -
Mitochondrial Function and Exercise in Cardiovascular Diseases
(Doctoral theses at NTNU;2019:221, Doctoral thesis, 2019)Kardiovaskulær sykdom er den vanligste dødsårsaken i verden, men epidemiologiske undersøkelser indikerer at trening kan redusere denne dødeligheten. Mekanismene bak den positive effekten av trening på kardiovaskulær helse ... -
Mitochondrial respiration after one session of calf raise exercise in patients with peripheral vascular disease and healthy older adults
(Journal article; Peer reviewed, 2016)Purpose: Mitochondria are essential for energy production in the muscle cell and for this they are dependent upon a sufficient supply of oxygen by the circulation. Exercise training has shown to be a potent stimulus for ... -
Mn-alginate gels as a novel system for controlled release of Mn2+ in manganese-enhanced MRI
(Journal article; Peer reviewed, 2012)The aim of the present study was to test alginate gels of different compositions as a system for controlled release of manganese ions (Mn2+) for application in manganese‐enhanced MRI (MEMRI), in order to circumvent the ... -
Model-Based Evaluation of Blood Velocity Estimation Techniques
(Doctoral thesis at NTNU;2015:81, Doctoral thesis, 2015)Pulsed Wave (PW) Doppler is a flow imaging modality in which the velocity distribution of the blood flow in a spatial region is displayed over time. In this work, methods for improvement of the conventional PW Doppler ... -
Models and Methods for Investigation of Reverberations in Nonlinear Ultrasound Imaging
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:217, Doctoral thesis, 2011)Models and methods for investigation of reverberations in nonlinear imaging techniques are presented in this thesis. Four independent papers provide insight on nonlinear propagation effects, a theoretical description of ... -
Moderate traumatic brain injury, acute phase course and deviations in physiological variables: an observational study
(Journal article; Peer reviewed, 2016)Background: Patients with moderate traumatic brain injury (TBI) are a heterogeneous group with great variability in clinical course. Guidelines for monitoring and level of care in the acute phase are lacking. The main ... -
Molecular and functional characterization of breast cancer through a combination of MR imaging, transcriptomics and metabolomics
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:14, Doctoral thesis, 2012)Breast cancer is the most frequent cancer among women in Norway. The outcome of this disease is heterogeneous. Some patients have slowly growing tumors which stay confined within the mammary gland, whereas others have ... -
Monitoring quality of care for peripheral intravenous catheters; feasibility and reliability of the peripheral intravenous catheters mini questionnaire (PIVC-miniQ)
(Journal article; Peer reviewed, 2019)Background Peripheral intravenous catheters (PIVCs) account for a mean of 38% of catheter associated bloodstream infections (CABSI) with Staphylococcus aureus, which are preventable if deficiencies in best practice are ... -
