The experiments presented in this thesis were designed to study diffusion processes in the human body under two distinct environmental conditions, i.e. free and restricted diffusion. In the typical timescales of milliseconds in magnetic resonance imaging (MRI), the diffusion of contrast agent molecules in blood vessels can be regarded as isotropic. However, reliably measured values of the diffusion coefficients have not been reported so far. With this thesis, a new approach to assess the diffusivity of Gd-DOTA as the most commonly used MRI contrast agent is presented. In order to enable direct observation of the complex by means of 1H NMR spectroscopy, the paramagnetic Gd3+ ion of Gd-DOTA was replaced by Ga3+. The diffusion coefficient of G...
