3. Quantitative imaging with PET : performance and applications of 76Br, 52Fe, 110mIn and 134La
Abstract : The use of positron emission tomography (PET) has so far mainly been limited to a few nuclides with short half-lives such as 11C and 18F. Certain applications require nuclides with longer half-lives, such as 76Br and 52Fe. READ MORE

4. The Utility of Ultrasmall Superparamagnetic Iron Oxide Contrast Agents for Cardiovascular Magnetic Resonance Imaging
Abstract : The purpose of this thesis was to investigate the utility of the Ultrasmall Superparamagnetic Iron Oxide Particle (USPIO), NC100150 Injection for assessment of macro- and microvascular morphology and function using magnetic resonance imaging. The feasibility of NC100150 Injection was tested for the following applications: Coronary angiography, Thrombus detection, Cardiac function, Myocardial perfusion, Assessment of myocardial blood volume and water exchange and finally assessment of endothelial integrity of the myocardium.

5. Proton Relaxation Properties of a Particulate Iron Oxide MR Contrast Agent in Different Tissue Systems : Implications for Imaging
Abstract : Knowledge of the relationship between in vivo contrast agent concentration and magnetic resonance (MR) signal response is an important requirement in contrast enhanced MR imaging in general and in MR based perfusion imaging in particular. This relationship is a complex function of the properties of the contrast agent as well as the structure of the target tissue. READ MORE
