  1. 1. Comparison of direct Fick's principle and thermodilution for calculating cardiac output in patients with pulmonary arterial hypertension.Does the assessment of cardiac index and pulmonary vascular resistance differ depending on which method is chosen?

    Master-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Gabriella Persson; [2023]
    Nyckelord :Pulmonary arterial hypertension; cardiac output; direct Fick´s principle; thermodilution;

    Sammanfattning : Pulmonary arterial hypertension (PAH) is an uncommon but serious disease that causes increased pressure in the pulmonary vessels and increased pulmonary vascular resistance (PVR), which in turn leads to right heart failure. At diagnosis, mean pulmonary artery pressure (mPAP) must be >20 mmHg, pulmonary artery wedge pressure (PAWP) ≤15 mmHg and PVR >2 Wood units (WU). LÄS MER

  3. 2. Kan musik påverka ångest, smärta eller de hemodynamiska effekterna i samband med bröst- och prostatabiopsier?

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Max Weberg; Tobias Mathisen; [2023]
    Nyckelord :Bröstbiopsi; musik; prostatabiopsi; smärta; terapi; ångest;

    Sammanfattning : Inledning: Bröst- och prostatacancer ökar snabbast hos kvinnor respektive män globalt. Cancerfallen förväntas öka med 47% från år 2020 till år 2040, detta gör att antal biopsier kommer att öka markant de kommande åren. LÄS MER

  4. 3. Generalized super-resolution of 4D Flow MRI : extending capabilities using ensemble learning

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Adam Hjalmarsson; Leon Ericsson; [2023]
    Nyckelord :4D Flow MRI; Ensemble learning; Super-resolution; Machine learning; Neural networks; 4DFlowNet;

    Sammanfattning : 4D Flow Magnet Resonance Imaging (4D Flow MRI) is a novel non-invasive technique for imaging of cardiovascular blood flow. However, when utilized as a stand-alone analysis method, 4D Flow MRI has certain limitations including limited spatial resolution and noise artefacts, motivating the application of dedicated post-processing tools.

  5. 4. Deep learning for temporal super-resolution of 4D Flow MRI

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Pia Callmer; [2023]
    Nyckelord :Temporal super-resolution; 4D Flow MRI; CNN; Artificial Intelligence; MRI; 4D flow; Temporal superupplösning; 4D flöde MRI; CNN; artificiell intelligens; MRI; 4D-flöde;

    Sammanfattning : The accurate assessment of hemodynamics and its parameters play an important role when diagnosing cardiovascular diseases. In this context, 4D Flow Magnetic Resonance Imaging (4D Flow MRI) is a non-invasive measurement technique that facilitates hemodynamic parameter assessment as well as quantitative and qualitative analysis of three-directional flow over time.

  7. 5. Lipoteichoic acid extraction from plasma : Chromatography techniques utilizing truncated derivates of antimicrobial peptides

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Gustav Sedelius; [2022]
    Nyckelord :antimicrobial peptides; chromatography; hemoperfusions; lipoteichoic acid; plasma; Sepsis;

    Sammanfattning : With increasing incidence rates aligned with poor prognosis; sepsis represents one of the biggest challenges in modern health care. It is a multifactorial syndrome defined as organ dysfunction caused by disturbed systemic response to an infection. LÄS MER
