This study introduces a new method for measuring lactate in vivo using specialized proton zero quantum coherence techniques. The method effectively eliminates lipid signals, demonstrating high performance for in vivo lactate quantification.

Area of Science:

  • Biomedical Engineering
  • Magnetic Resonance Imaging
  • Metabolomics

Background:

  • Accurate in vivo lactate measurement is crucial for understanding metabolic processes in various diseases.
  • Existing methods often suffer from interference, particularly from lipid signals, limiting their specificity.

Purpose of the Study:

  • To develop and validate a novel in vivo method for selective lactate detection.
  • To overcome the challenge of lipid signal interference in proton magnetic resonance spectroscopy (MRS).

Main Methods:

  • Utilized proton zero quantum coherence (ZQC) techniques for enhanced spectral editing.
  • Employed a surface coil for signal reception.
  • Implemented slice-selective localization to define the region of interest.

Main Results:

  • Successfully achieved selective detection of lactate signals in vivo.
  • Demonstrated effective suppression of confounding lipid signals.
  • Acquired spectra confirmed the good performance and specificity of the developed method.

Conclusions:

  • The proton ZQC technique provides a robust and selective approach for in vivo lactate measurement.
  • This method holds promise for improved diagnostic capabilities in conditions involving altered lactate metabolism.
