Growth dynamics of untreated meningiomas
(Journal article; Peer reviewed, 2023)Abstract Background Knowledge about meningioma growth characteristics is needed for developing biologically rational follow-up routines. In this study of untreated meningiomas followed with repeated magnetic resonance ... -
Automated 2-D and 3-D Left Atrial Volume Measurements Using Deep Learning
(Journal article; Peer reviewed, 2023)Objective: Echocardiography, a critical tool for assessing left atrial (LA) volume, often relies on manual or semi-automated measurements. This study introduces a fully automated, real-time method for measuring LA volume ... -
Instant Detection of Cerebral Blood Flow Changes in Infants with Congenital Heart Disease during Transcatheter Interventions
(Journal article; Peer reviewed, 2024)Background: Transcatheter interventions are increasingly used in children with congenital heart disease. However, these interventions can affect cardiac output and cerebral circulation. In this pilot study, we aimed to ... -
Association between patient-reported cognitive function and location of glioblastoma
(Journal article; Peer reviewed, 2023)Objective cognitive function in patients with glioblastoma may depend on tumor location. Less is known about the potential impact of tumor location on cognitive function from the patients’ perspective. This study aimed to ... -
Treatment of Liver Metastases With Focused Ultrasound and Microbubbles in Patients With Colorectal Cancer Receiving Chemotherapy
(Journal article; Peer reviewed, 2023)Objective: Pre-clinical trials have obtained promising results that focused ultrasound (FUS) combined with microbubbles (MBs) increases tumor uptake and the therapeutic effect of drugs. The aims of the study described here ... -
Quantification of Flow Rates and Flow Volumes in Valve Regurgitation Using 3-D High Frame-Rate Ultrasound
(Journal article; Peer reviewed, 2023)Valve regurgitation is a cardiac condition caused by the incomplete closure of a cardiac valve. Untreated, this condition may result in cardiac failure. Regular monitoring of this condition is essential in guiding the ... -
Analysis of Aberration Effects on Flow Imaging and Quantification in Echocardiography
(Journal article; Peer reviewed, 2023)In medical ultrasound, aberration is a phenomenon that causes distortion of the ultrasound wavefront as it travels through an inhomogeneous medium. Aberration has been investigated since the 1960s and is known as a major ... -
Aligning peripheral intravenous catheter quality with nursing culture—A mixed method study
(Journal article; Peer reviewed, 2024)Aim: To explore barriers and facilitators that influence adherence to evidence-based guidelines for peripheral intravenous catheter care in different hospital wards. Design: Sequential explanatory mixedmethod study design, ... -
Real-time feedback on chest compression efficacy by hands-free carotid Doppler in a porcine model
(Journal article; Peer reviewed, 2024)Aim: Current guidelines for cardiopulmonary resuscitation (CPR) recommend a one-size-fits-all approach in relation to the positioning of chest compressions. We recently developed RescueDoppler, a hands-free Doppler ultrasound ... -
Femoral Nailing in a Porcine Model Causes Bone Marrow Emboli in the Lungs and Systemic Emboli in the Heart and Brain
(Journal article; Peer reviewed, 2024)Background: Shaft fractures of the femur are commonly treated with intramedullary nailing, which can release bone marrow emboli into the bloodstream. Emboli can travel to the lungs, impairing gas exchange and causing ... -
Doppler ultrasound for quantification of fluid influx/ efflux from borehole fractures using LWD tools
(Doctoral theses at NTNU;2024:221, Doctoral thesis, 2024)The work presented in this thesis is aimed at studying the potential for applying ultrasonic Doppler measurements during a borehole drilling process using ultrasonic logging-while-drilling (LWD) tools. The primary intention ... -
Effects of High-Intensity Interval Training on Coronary Atheromatous Plaques: Results from a randomized clinical trial
(Doctoral theses at NTNU;2024:216, Doctoral thesis, 2024)Atherosclerosis is a chronic, progressive disease characterized by the deposition of cholesterol and various inflammatory cells within the vessel walls, leading to fatty deposits (plaques) and calcifications. When the ... -
Chronic kidney disease and risk of bloodstream infections and sepsis: a 17-year follow-up of the population-based Trøndelag Health Study in Norway
(Journal article; Peer reviewed, 2024)Purpose: Bloodstream infections (BSI) and sepsis are important causes of hospitalization, loss of health, and death globally. Targetable risk factors need to be identified to improve prevention and treatment. In this study, ... -
Deep Learning Applications for the Assessment of Valvular Heart Disease using Transthoracic Echocardiography
(Doctoral theses at NTNU;2024:198, Doctoral thesis, 2024)Valvular heart disease (VHD) is a class of diseases that affect the heart valves, and are associated with a reduced cardiac output and a poor prognosis for the afflicted patients. Transthoracic echocardiography (TTE) is ... -
The effect of a music-based caregiving intervention on pain intensity in nursing home patients with dementia. A cluster-randomized controlled study
(Peer reviewed; Journal article, 2024)Treatment of chronic pain in patients with dementia is challenging because they have reduced ability to report pain and are particularly vulnerable to side effects of analgesics. Different types of music-based therapy have ... -
Right ventricular energetics using blood speckle tracking in pediatric congenital heart disease
(Doctoral theses at NTNU;2024:190, Doctoral thesis, 2024)This thesis is composed of three studies of right ventricular (RV) energetics in pediatric patients with congenital heart disease (CHD), using blood speckle tracking (BST). The objectives were to describe the RV energetics ... -
Exercise training and high-sensitivity cardiac troponin-I in patients with heart failure with reduced ejection fraction
(Journal article; Peer reviewed, 2024)Aims: The aims of this sub-study of the SMARTEX trial were (1) to evaluate the effects of a 12-week exercise training programme on serum levels of high sensitivity cardiac troponin I (hs-cTnI) in patients with moderate ... -
