MR assessment of end-organ damage in the metabolic syndrome and diabetes mellitus

Abstract

The first part of this thesis focuses on assessing end-organ damage in individuals with the metabolic syndrome and diabetes mellitus using magnetic resonance imaging (MRI) and spectroscopy (1H-MRS). We performed cross sectional and intervention studies to investigate the contribution of obesity, dietary conditions, metabolic environment and exogenous disruptors (chemotherapy) to cardiovascular end-organ damage and the reversibility of this damage with a low caloric diet. The effects of interventions, dietary as well as non-dietary, were explored using imaging technology. As ethnicity is an important aspect of the pathophysiology in diabetes mellitus, we also examined the influence of ethnic factors on diabetes mellitus and its complications. The second part of this thesis focuses on safety, feasibility and implementation of innovative MR techniques at higher field strengths for assessment of cardiovascular disease.
