Area of Science:

  • Medical Imaging
  • Diffusion MRI
  • Renal Physiology

Background:

  • Kidney diffusion imaging is crucial for clinical diagnosis.
  • Existing methods face challenges like abdominal susceptibility variations and motion sensitivity.
  • Acquisition time is limited to a single breath-hold.

Purpose of the Study:

  • To characterize human kidney diffusion anisotropy using diffusion-weighted imaging.
  • To implement a novel segmented EPI protocol for high-resolution diffusion imaging within one breath-hold.
  • To overcome limitations of conventional diffusion imaging in the abdomen.

Main Methods:

  • Utilized a diffusion-weighted, single-shot echo planar imaging (EPI) sequence.
  • Implemented an isotropic, diffusion-weighted, segmented EPI protocol.

  • Acquired apparent diffusion tensor (ADT) data within a single breath-hold.

    • Main Results:

    • Fractional anisotropy (FA) values were 0.22 ± 0.12 (cortex) and 0.39 ± 0.11 (medulla).
    • Apparent diffusion coefficient (ADC) values were 2.89 ± 0.28 x 10⁻⁹ m²/s (cortex) and 2.18 ± 0.36 x 10⁻⁹ m²/s (medulla).
    • The novel protocol enabled high-resolution diffusion-weighted images within one breath-hold.

    Conclusions:

    • Diffusion anisotropy varies between human kidney cortex and medulla.
    • Rotationally invariant diffusion measurements are essential for clinical kidney applications.
    • The developed segmented EPI protocol shows promise for overcoming current diffusion imaging limitations in the abdomen.
