Full textProton magnetic resonance chemical shift imaging (CSI) at short time (TE) in vivo allows characterization of the spatial distribution of strongly J-coupled and short T2 biomarkers relevant to healthy or pathologic metabolism. We have developed a volumetric CSI technique for human brain studies at 3 Tesla in an experiment time compatible with patient examination. Pulse sequence modules for selection of the volume of interest (PRESS and semi-LASER), and for suppression of water and outer volume signals were implemented and optimized. The use of spiral K-space trajectories allowed acquisition speed-up by simultaneous encoding of spatial and spectral dimensions. Techniques of calibration and optimisation of the effective trajectory were developed, as well as an algorithm for reconstruction of 2 or 3 D spatial – 1 D spectral data sets. The method was validated in vivo on human brain with TEs of 17 ms (PRESS) or 32 ms (semi-LASER), on healthy subjects. Good saturation of subcutaneous lipids was obtained. Semi-LASER, by its use of adiabatic RF pulses, brought both sharper spatial selection profiles less sensitive to B1 inhomogeneity, and reduced chemical shift displacement errors. Using the measured trajectory for data reconstruction reduced artefacts associated with gradient hardware imperfections. NAA, Creatine, Choline, myo-Inositol and Glutamate/Glutamine were significantly quantified both with PRESS and semi-LASER. Clinical application of short TE volumetric spiral CSI at 3T can be considered

The geometric distortion in echo-planar imaging (EPI) and its correction are systematically investigated in this thesis. EPI is one of the fastest MRI acquisition pulse sequence and is widely used for dynamic studies. However, in the presence of the field inhomogeneities, the EPI k-space energy peaks are displaced, which result in geometric distortions in the reconstructed images. Here we use the k-space energy spectrum analysis to calculate the k-space energy displacement in EPI. The calculated k-space energy displacement map can be converted to the field inhomogeneity map, which can then be applied to correct the EPI distortions using a phase modulation post-processing procedure. The EPI data corrected with the previously developed k-space energy spectrum based method, however, may have residual distortions due to an unknown B0 reference and the accumulated errors during the integration procedure. To further improve the accuracy and reliability of EPI distortion correction, we propose to combine the k-space energy spectrum analysis and an altered EPI acquisition strategy, in which the central part of the k-space is double sampled. In this approach, the B0 reference can be obtained from the embedded low-resolution double-TE data. In addition, the error accumulation in the integration procedure can be minimized. Experimental results show that the new method can effectively remove EPI geometric distortions.
