Biomechanics of Cardiac Remodelling in Heart Failure
Heart failure (HF) occurs when cardiac output does not meet the requirements of the body. HF is the result of maladaptive cardiac remodelling that alters myocardial structure and ventricular function. Current HF treatments were developed targeting patients with systolic dysfunction, but these …

Quantification of cardiac magnetic resonance imaging perfusion in the clinical setting at 3T
Dynamic contrast enhanced (DCE) cardiac magnetic resonance imaging (MRI) is well-established as a non-invasive method for qualitatively detecting obstructive coronary artery disease (CAD) which can impair myocardial blood flow and may result in myocardial infarction. Mathematical modelling of …

Cardiac magnetic resonance imaging for non-invasive detection of myocardial fibrosis
… the heart muscle, leading ultimately to impaired cardiac function, heart disease and heart failure. Therefore, it is paramount to develop non-invasive technology for the early detection of myocardial fibrosis in order to slow, treat or prevent heart disease and heart failure. Currently, detection …

Alternative Lead Systems for Diagnostic Electrocardiography: Validation and Clinical Applicability
… and most frequently used tools for diagnosing cardiac diseases, although several different examination modalities in cardio¬logy have been developed over the years. The standard ECG uses 10 electrodes placed on well-defined positions on the body, 6 on the torso and 4 distally on the limbs. Both …

Imaging Post-Infarct Myocardial Inflammation with ⁶⁸Ga-DOTATATE PET/MRI and insights into COVID-19 associated myocardial injury
i) Post-Infarct Myocardial Inflammation and Imaging Background: Inflammation and its resolution modulate post-infarct myocardial injury. An excessive or prolonged inflammatory phase after myocardial infarction (MI) may contribute to adverse cardiac remodelling. <sup>68</sup>Ga-DOTATATE is a PET …

Distortion-optimal parallel MRI with sparse sampling: from adaptive spatio-temporal acquisition to self-calibrating reconstruction
… and reconstruction that pertain to parallel magnetic resonance imaging (pMRI). The first part of this dissertation addresses adaptive design of spatio-temporal acquisition and reconstruction in model-based pMRI wherein the signal model is a sparse support. We develop a highly-accelerated …
