Main parameters and performance indicators

Spectral Frequency: Characteristic resonance frequency of nuclei (e.g., 1H, 13C) used for identification.Chemical Shift: The position of a spectral peak relative to a reference compound, indicating the chemical environment of the nucleus.Spectral Resolution: The ability to distinguish between closely spaced peaks in the spectrum.

Open problems

Quantification of absolute metabolite concentrations in vivo.Improving spatial resolution and signal-to-noise ratio in clinical settings.
