J. Lassner vivo NMR spectroscopy (MRS). Because of the non-invasive nature of MRS, clinical measurements of absolute concentrations can be made (and repeated if required) on tissues such as neonatal brain that are normally inaccessible to biopsy. Furthermore, because observations can be made on tissue in situ

G. Sprottet critical piece of instrumentation for the in-vivo spectroscopist is the NMR probe. The need to perform quick and reliable experiments, particularly in the clinical setting, makes probe sensitivity critical. Many studies involve the use of more than one nucleus. Typically, proton NMR is used to shi

H. Bergmannignals to a plane of preselected thickness and location. How and why DRESS came about is discussed in the first section. The two factors affecting the definition of the plane, the surface coil and the slice selection, are analyzed in detail in the description section, where the problems of shimming

R. Dennhardtn vivo. However, the 100 M water resonance, molar lipid resonances, large number of compounds containing .H nuclei, extensive homonuclear coupling and narrow chemical shift range (10 ppm) of biologically active metabolites provides major barriers to uniquely resolving metabolite resonances of intere

M. Zenzl cations important for cell function: Na., K., H., Ca. and Mg.. Intra- and extracellular amounts of Na. or K. can be measured simultaneously using .Na or .K NMR by placing a frequency shift reagent in the extracellular space; a comparison of three anionic chelate complexes of paramagnetic lanthanid
