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凶兆 发表于 2025-3-25 10:27:20
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 shiAtrium 发表于 2025-3-25 13:59:05

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 intereCOW 发表于 2025-3-26 11:02:28
