The South African Cardiovascular Magnetic Resonance (SA-CMR) Registry: An Interim Analysis of Clinical Utility, Indications and Baseline Characteristics of Patients Undergoing CMR in a Single Centre in South Africa
Background Cardiovascular magnetic resonance (CMR) is a clinically useful imaging modality that is fast becoming a routine tool in clinical practice. In 2013, the results of the first multi-national registry, EuroCMR, were published. The study highlighted the clinical significance and impact of CMR …

Coal mass rating with regards to outburst and coal burst
… coal seams were measured using Coal Mass Rating (CMR). The CMR is a ratio analysis of Uniaxial Compressive Strength (UCS) results that produces three CMR metrics: CMR FROM UCS, CMR from Young’s Modulus, and combined CMR. The first hypothesis tested for a correlation between burst coal with higher …

Non-invasive Cardiovascular Magnetic Resonance Imaging in Patients with Ischemic Heart Disease
… cardiovascular magnetic resonance (OS-CMR) or commonly referred to as Blood-Oxygen Level Dependent CMR (BOLD-CMR), is a non-invasive imaging technique that does not require contrast agents or radiation. Therefore, the purpose of this thesis was to build upon the understanding of …

Cardiovascular Magnetic Resonance Guided Revascularisation
… Established Cardiovascular Magnetic Resonance (CMR) techniques already provide much of the relevant functional information and the absence of ionising radiation makes CMR ideal for serial examinations. However, new CMR techniques continue to emerge, and require appropriate clinical …

Novel Phenotyping of the Myocardium by Diffusion Tensor Cardiovascular Magnetic Resonance
… tensor cardiovascular magnetic resonance (DT-CMR) is a novel, non-invasive technique informing about myocardial microstructure, including cardiomyocytes and sheetlets. Few in-vivo human studies exist. This research aims to investigate microstructural changes in disease and assess the utility …

Computer Aided Analysis of Late Gadolinium Enhanced Cardiac MRI
… enhanced (LGE) cardiac magnetic resonance (CMR) imaging can directly visualize and thus discriminate non-viable myocardium (i.e., infarcts) from normal myocardium via hyper-enhanced intensities. Since manual analysis of LGE CMR images is not only time-consuming but also subject to …

Quantitative and Qualitative Assessment of the Myocardium at Risk
… treatment. Cardiac magnetic resonance imaging (CMR) has the opportunity to accurately assess both the myocardium at risk as well as the infarct size. This thesis has contributed to the knowledge on quantification of the myocardium at risk and subsequently myocardial salvage with the use of CMR …

Evaluation of alterations in cardiovascular structure and function in end-stage renal failure.
… in cardiovascular magnetic resonance imaging (CMR), we evaluated the cardiovascular sequelae of arterio-venous fistula formation in advanced chronic kidney disease, and the impact of elective arterio-venous fistula ligation following successful renal transplantation. Furthermore, we undertook …

Mechanical Dyssynchrony in Heart Failure and Implications for Response and Guidance of Cardiac Resynchronisation Therapy
… LV lead position. Cardiac magnetic resonance (CMR) imaging can quantify global myocardial dyssynchrony in different modalities; volume change, muscle thickening and strain. Understanding how these measures of dyssynchrony relate to each other is important when considering how they can assist …

Dobutamine stress magnetic resonance imaging in tetralogy of fallot
… the role of cardiac magnetic resonance (CMR) imaging in the assessment of patients with surgically repaired tetralogy of Fallot (TOF). CMR has become a powerful tool in the serial assessment of this group of patients and provides important information on cardiac structure and function …

The role of obscured activity in galaxy formation
… eventually form the colour-magnitude relation (CMR) in local galaxy clusters. I survey galaxies that lie on the CMR in nine massive clusters at z~0.2, environments in which the build-up of the faint end of the CMR is still underway. I show that there are relatively few dwarf galaxies on the CMR …
