    Area of Science:

    • Medical imaging
    • Biophysical techniques
    • Nuclear magnetic resonance spectroscopy

    Background:

    • High-resolution spectral localization in human subjects presents challenges due to sample size and geometry impacting probe design.
    • Existing spectroscopic methods may not be optimal for large biological samples like the human body.

    Purpose of the Study:

    • To describe a novel spectroscopic localization method for in vivo human samples.
    • To present a new surface-coil probe designed for large sample geometries.
    • To demonstrate the feasibility of obtaining spatially resolved metabolite spectra in human subjects.

    Main Methods:

    • Utilized the method of rotating frame imaging for spectroscopic localization.
    • Developed and employed a novel surface-coil probe suitable for large samples.

  • Acquired 31P (Phosphorus-31) spectra from the thorax of a human subject.

    • Main Results:

    • Successfully resolved 31P spectra from distinct regions within the human thorax, specifically identifying signals from the liver and intercostal muscles.
    • Demonstrated the capability to obtain spatially resolved metabolite spectra in vivo.
    • Achieved acquisition times suitable for clinical patient examination.

    Conclusions:

    • The described spectroscopic localization method, combined with the novel surface-coil probe, is effective for in vivo human studies.
    • This technique allows for non-invasive, spatially resolved metabolic analysis in human subjects.
    • The method offers a viable approach for clinical applications requiring rapid metabolic imaging.
