Summary

The World Health Organization updated the thyroid ultrasound correction factor. This study compares different factors to MDCT measurements, proposing an optimal factor of 0.529 for thyroid volume assessment.

Area of Science:

  • Endocrinology
  • Radiology
  • Medical Imaging

Background:

  • Thyroid volume assessment commonly uses sonography with an ellipsoid formula.
  • A correction factor is applied in this formula, with the World Health Organization recently changing it from 0.524 to 0.479.

Purpose of the Study:

  • To compare thyroid volume measurements using different correction factors with automated measurements from multi-detector computed tomography (MDCT).
  • To determine an optimal correction factor for thyroid volume assessment using sonography.

Main Methods:

  • Thyroid volumes were measured using sonography with varying correction factors.
  • These measurements were compared against automated thyroid volume measurements obtained via MDCT.

Main Results:

Related Experiment Videos

  • The study identified an acceptable range for correction factors between 0.494 and 0.554.
  • A proposed correction factor of 0.529 was found to be optimal when using the ellipsoid formula for thyroid volume assessment.

Conclusions:

  • The optimal correction factor for thyroid volume assessment using the ellipsoid formula is proposed as 0.529.
  • Correction factors within the range of 0.494-0.554 are considered acceptable for thyroid volume sonography.
