Book Description
Magnetic Resonance Spectroscopy: Tools for Neuroscience Research and Emerging Clinical Applications is the first comprehensive book for non-physicists that addresses the emerging and exciting technique of magnetic resonance spectroscopy. Divided into three sections, this book provides coverage of the key areas of concern for researchers. The first, on how MRS is acquired, provides a comprehensive overview of the techniques, analysis, and pitfalls encountered in MRS; the second, on what can be seen by MRS, provides essential background physiology and biochemistry on the major metabolites studied; the final sections, on why MRS is used, constitutes a detailed guide to the major clinical and scientific uses of MRS, the current state of teh art, and recent innovations. Magnetic Resonance Spectroscopy will become the essential guide for people new to the technique and give those more familiar with MRS a new perspective. Chapters written by world-leading experts in the field Fully illustrated Covers both proton and non-proton MRS Includes the background to novel MRS imaging approaches

Book Description
Magnetic resonance imaging (MRI) is a medical imaging technique that is used to obtain images of soft tissue throughout the body. Since its development in the 1970s, MRI has gained tremendous importance in clinical practice because it can produce high quality images of diagnostic value in an ever expanding range of applications from neuroimaging to body imaging to cancer. By far the dominant signal source in MRI is hydrogen nuclei in water. The presence of water at high concentration (-50M) in body tissue, combined with signal contrast modulation induced by the local environment of water molecules, accounts for the success of MRI as a medical imaging modality. As opposed to conventional MRI, which derives its signal from the water component, magnetic resonance spectroscopy (MRS) acquires the magnetic resonance signal from other chemical components, most frequently various metabolites in the brain, but also signals from tumors in breast and prostate. The spectroscopic signal arises from low concentration (-1 - 10mM) compounds, but in spite of the challenges posed by the resulting low signal-to-noise ratio (SNR), the development of MRS is motivated by the desire to directly observe signal sources other than water. The combination of MRS with spatial encoding is called magnetic resonance spectroscopic imaging (MRSI). MRSI captures not only the relative intensities of metabolite signals at each voxel, but also their spatial distributions. While MRSI has been proven to be clinically useful, it suffers from fundamental tradeoffs due to the inherently low SNR, such as long acquisition time and low spatial resolution. In this thesis, techniques that combine benefits from both model-based reconstruction methods and regularized reconstructions with prior knowledge are proposed and demonstrated for MRSI. These methods address constraints on acquisition time in MRSI by undersampling data during acquisition in combination with improved image reconstruction methods.
