Exponential decay modeling in spectroscopy

摘要

The invention permits measurement of changes in chemical concentrations where the chemicals have the same resonance peak in magnetic resonance spectroscopy. Using this approach, MRS techniques with higher resolution can be used, even though they fail to resolve chemicals of interest into different peaks. The invention can be applied to diagnose diseases, e.g., metabolic disorders, and to measure time-dependent chemical response to sensory or pharmaceutical stimuli.
