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 ... -
Modeling the diffusion-weighted imaging signal for breast lesions in the b = 200 to 3000 s/mm 2 range: quality of fit and classification accuracy for different representations
(Peer reviewed; Journal article, 2020)Purpose To evaluate different non‐Gaussian representations for the diffusion‐weighted imaging (DWI) signal in the b‐value range 200 to 3000 s/mm2 in benign and malignant breast lesions. Methods Forty‐three patients ... -
Modelling acoustic radiation from vibrating surfaces around coincidence: Radiation into fluids
(Peer reviewed; Journal article, 2023)It is well-known that vibrating surfaces generate sound waves in adjacent fluids. According to the classical radiation model, the nature of these waves depends on whether the vibration’s phase speed cv is above (supersonic) ... -
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 and severe traumatic brain injury in general hospitals: a ten-year population-based retrospective cohort study in central Norway
(Peer reviewed; Journal article, 2022)Background Patients with moderate and severe traumatic brain injury (TBI) are admitted to general hospitals (GHs) without neurosurgical services, but few studies have addressed the management of these patients. This ... -
Moderate continuous or high intensity interval exercise in heart failure with reduced ejection fraction: Differences between ischemic and non-ischemic etiology
(Peer reviewed; Journal article, 2022)Background Exercise for heart failure (HF) with reduced ejection fraction (HFrEF) is recommended by guidelines, but exercise mode and intensities are not differentiated between HF etiologies. We, therefore, investigated ... -
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 ... -
Monitoring variability in parameter estimates for lumped parameter models of the systemic circulation using longitudinal hemodynamic measurements
(Journal article; Peer reviewed, 2023)Background Physics-based cardiovascular models are only recently being considered for disease diagnosis or prognosis in clinical settings. These models depend on parameters representing the physical and physiological ... -

Mononuclear but Not Polymorphonuclear Phagocyte Depletion Increases Circulation Times and Improves Mammary Tumor-Homing Efficiency of Donor Bone Marrow-Derived Monocytes
(Peer reviewed; Journal article, 2019)Tumor associated macrophages are an essential part of the tumor microenvironment. Consequently, bone marrow-derived monocytes (BMDMs) are continuously recruited to tumors and are therefore seen as ideal delivery vehicles ... -
Morphine for cancer pain
(Dissertations at the Faculty of Medicine, 0805-7680; 209, Doctoral thesis, 2002)The objectives of the present study were: I. To assess the effect from start of morphine treatment to cancer pain patients in respect to time needed for dose-finding, dose needed for pain control and adverse symptoms. II. ... -
Mortality in Patients with Acute Coronary Syndrome—A Prospective 5-Year Follow-Up Study
(Peer reviewed; Journal article, 2023)Our objective was to compare long-term outcomes in patients with non-ST-elevation myocardial infarction (NSTEMI) and ST-elevation myocardial infarction (STEMI) between two time periods in Southern Norway. There are limited ... -

MR fingerprinting og diagnostikk av prostatakreft
(Bachelor thesis, 2021)Prostatakreft er den vanligste kreftformen blant menn og er et problem som påvirker mange liv. For å diagnostisere sykdommen har det vært en økning av kvantitativ MR de siste årene. Fortsatt er det ikke utviklet et ... -
MR imaging and spectroscopy in prostate and colon cancer diagnostics
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:251, Doctoral thesis, 2012)Prostate and colorectal cancers are among the most common cancers in Norway and are also leading causes of cancer related deaths. In prostate cancer there are currently no accurate clinical methods to discriminate patients ... -
