A subspace approach to spectral quantification for MR spectroscopic imaging
The problem of spectral quantification for magnetic resonance spectroscopic imaging (MRSI) is addressed in this thesis. We present a novel approach to solving this problem, incorporating both spatial and spectral prior information. More specifically, a new signal model is proposed which represents …

Accelerated J-resolved proton magnetic resonance spectroscopic imaging
… as a powerful tool for noninvasive mapping of metabolites and neurotransmitters. A fundamental challenge of conventional 1H-MRSI is that resonances from different molecules overlap with one another in the crowded chemical shift frequency spectrum, which will lead to great difficulties in …
