Ultrasound Attenuation Imaging Tracks Hepatic Steatosis

Attenuation imaging increased with visually graded steatosis severity in pediatric patients, but findings were not validated against MRI-PDFF or biopsy.

    Ultrasound attenuation imaging values increased with hepatic steatosis severity in pediatric patients with overweight or obesity.

  • 2

    The study included 97 children with overweight, 292 with obesity, and 264 healthy-weight controls, totaling 653 participants.

  • 3

    Median attenuation imaging values were 0.51 dB/cm/MHz in healthy-weight controls and increased to 0.64 dB/cm/MHz in children with obesity.

  • 4

    Attenuation imaging values correlated with several metabolic measures, with the strongest correlation observed with alanine aminotransferase.

  • 5

    The study's limitations included lack of MRI-PDFF validation and single-center design, suggesting results may not be broadly generalizable.
