  1. 1. Domain Adaptation for Multi-Contrast Image Segmentation in Cardiac Magnetic Resonance Imaging

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Thomas Proudhon; [2023]
    Keywords : Cardiac Magnetic Resonance Imaging; Deep Learning; Domain Adaptation; Unsupervised Segmentation; Image-to-image Translation;

    Abstract : Accurate segmentation of the ventricles and myocardium on Cardiac Magnetic Resonance (CMR) images is crucial to assess the functioning of the heart or to diagnose patients suffering from myocardial infarction. However, the domain shift existing between the multiple sequences of CMR data prevents a deep learning model trained on a specific contrast to be used on a different sequence. READ MORE

  3. 2. A viscoelastic evaluation of an injectable disulfide cross-linked thiol-collagen hydrogel: for tissue bulking post-myocardial infarction to prevent heart failure

    University essay from Uppsala universitet/Makromolekylär kemi

    Author : Karin Dungner; [2023]
    Keywords : ;

    Abstract : Cardiovascular diseases are currently the leading cause of death globally. Progression of the disease affects the composition and function of the heart and in many cases subsequently results in heart failure over time where a heart transplant is vital. Therefore, there is a need for medical treatments to stop the progression of the disease. READ MORE

  4. 3. Feasibility of quantitative 99mTc-DPD scintigraphy SPECT/CT for assessing the burden of ATTR cardiac amyloidosis

    University essay from Umeå universitet/Radiofysik

    Author : Sajad Kadhim Khalaf; [2023]
    Keywords : QSPECT; Amyloidosis; ATTR; LVMI; Recovery Coefficient; SUV; Calibration;

    Abstract : Background: Amyloid transthyretin (ATTR) cardiomyopathy is caused by the deposition of misfolded proteins, known as amyloid fibrils, in the myocardium. Quantitative Single Photon Emission Computed Tomography (QSPECT) utilizing 99mTc-DPD scintigraphy has the potential to assess ATTR-suspected cardiac amyloidosis (CA). READ MORE

  5. 4. Automatic Left Ventricle Segmentation of Long-Axis Cardiac MRI-Images

    University essay from Lunds universitet/Matematik LTH

    Author : Ruben Bergengrip; [2021]
    Keywords : MRI; Magnetic resonance imaging; Deep Learning; Machine learning; U-net; CNN; Semantic segmentation; Segmentation; Global longitudinal strain; GLS; strain; AV-plane displacement; AVPD; long-axis; left ventricle; LV; cardiac MRI; CMR; Image analysis; Technology and Engineering;

    Abstract : Over 30 % of all deaths worldwide are related to cardiovascular diseases and they are the leading cause of death. Therefore, research into treatment, diagnosis and prognostication of these diseases are of critical importance. One way to examine the cardiovascular system is through the use of Magnetic Resonance Imaging (MRI). READ MORE

  6. 5. Mechanisms of action of β-blockers for the treatment of heart failure

    University essay from Linköpings universitet/Biologi

    Author : Jonas Burman; [2020]
    Keywords : Apoptosis; angiotensin II; β-antagonist; beta-blocker; Heart failure; Mechanism;

    Abstract : Heart failure is a syndrome in which the heart is unable to supply the entire body with oxygen. It is manifested in shortness of breath and exercise intolerance. One class of drugs that have proven effective in managing the progression of heart failure is β-blockers. READ MORE
