In vivo1H) MR spectroscopy (MRS) has proton (evolved as a non-invasive tool for diagnosis and for biochemical characterization of breast cancer. Water-to-fat ratio, fat and water fractions and choline containing compounds (tCho) have been identified as diagnostic biomarkers of malignancy.

MR spectroscopy provides a measure of brain chemistry. The most common nuclei that are used are 1 H (proton), 23 Na (sodium), 31 P (phosphorus). Proton spectroscopy is easier to perform and provides much higher signal-to-noise than either sodium or phosphorus.

Malignant tissues contain high concentration of choline containing compounds that can be used as a biochemical marker. MRS helps to increase the specifi city of MRI in lesions larger than 1cm and to monitor the tumor response. Clinical MR imaging systems are typically provided with a body coil for transmit and an array of receiver elements to enable state-of-the-art MR imaging. The use of 32 (or more) channel receive-coil arrays can boost SNR, particularly for cortical regions close to the surface of the brain (199).

Clinical MR Spectroscopy: Techniques and Applications is an excellent, well-organized textbook introducing the reader to principles, physics, and practical clinical applications of MR spectroscopy (MRS). The five well-respected authors, from the United States and Italy, have written a book that can be used both by readers with no prior MRS background and those knowledgeable in spectroscopy
