Abstract:
The work described in this thesis was initiated in an attempt to overcome the limitations imposed upon NMR spectroscopy by magnetic field inhomogeneity in two specific areas: high resolution spectroscopy in isotropic liquids, and chemical shift resolved NMR imaging in isotropic liquids. In both cases magnetic field inhomogeneity may degrade the resolution of spectra to such an extent that no useful information can be obtained from them. In high resolution NMR spectroscopy it is necessary to be able to extract accurately the parameters present within the spectrum such as chemical shifts, coupl

Magnetic resonance imaging (MRI) can be used to image diffusion in liquids, such as water in brain structures.

For anisotropic environments, the eigenvector of D corresponding to the largest eigenvalue indicates the preferred direction of diffusion.<br>This thesis describes the design and implementation of diffusion tensor imaging on a clinical MRI system.

Magnetic resonance imaging (MRI) is used to image parts of the body using only electromagnetic interaction with the body's own atomic nuclei (hydrogen protons, in particular).

The resolution of the obtained image is proportional to the number of locations and hence to the time allowed for data acquisition; and the bandlimit imposed by restricting the acquisition time is more severe in one

Initially, complexes containing a trifluoromethyl group were examined for 19F MRI/S, due to the large chemical shift range, favourable NMR properties, and the absence of a background signal in vivo. The use of paramagnetic lanthanide ions increases relaxation rates, allowing faster acquisition times and increased signal intensity per unit time. In addition, chemical shift non-equivalence is enhanced, which is important for the development of responsive probes. Exampl
