    Area of Science:

    • Medical Imaging
    • Biophysics
    • Magnetic Resonance

    Background:

    • Proton chemical shift imaging (CSI) is crucial for differentiating water and lipid signals.
    • Existing CSI techniques can be complex and time-consuming.
    • Simultaneous water-lipid separation is highly desirable for various clinical applications.

    Purpose of the Study:

    • To develop and validate a modified multisection proton chemical shift imaging technique.
    • To achieve simultaneous acquisition of separate water and lipid images.
    • To demonstrate the feasibility of this technique on a clinical 1.5-T MRI system.

    Main Methods:

    • Utilized a clinical 1.5-T whole-body magnetic resonance imaging unit.
    • Adapted the standard multisection spin-warp technique.
    • Incorporated a sinc pulse or soft square pulse and a homospoil gradient into the pulse sequence.

    Main Results:

    • Successfully performed multisection proton chemical shift imaging.
    • Generated separate, distinct water and lipid images.
    • Presented phantom and human anatomic images demonstrating technique efficacy.

    Conclusions:

    • The modified multisection CSI technique enables simultaneous water and lipid image acquisition.
    • This method offers a practical approach for enhanced tissue characterization.
    • The presented results support its potential clinical utility in magnetic resonance imaging.
