This study introduces a simple, cost-effective classification for sub-endometrial vascularization using Power Doppler. The validated method shows excellent agreement among observers, suggesting clinical utility.

Area of Science:

  • Reproductive endocrinology and imaging
  • Gynecology

Background:

  • Sub-endometrial vascularization plays a role in endometrial receptivity.
  • Accurate quantification of vascularization is crucial for clinical assessment.

Purpose of the Study:

  • To validate a simple and cost-effective classification system for sub-endometrial vascularization using Power Doppler energy levels.
  • To assess the reliability and agreement among observers for this classification system.

Main Methods:

  • Fifty-two women with regular menses were examined during the mid-luteal phase.
  • A five-category classification (I-V) based on the percentage area of sub-endometrial signal was used.
  • Three blinded observers independently evaluated and classified endometrial images, with Kappa test used for agreement analysis.

Main Results:

  • No significant differences in age, body mass index (BMI), or endometrial thickness were observed across the Power Doppler classification groups.
  • The Kappa test yielded a Kappa value of 0.70, indicating excellent agreement among examiners (P = 0.0001).
  • The classification system proved to be simple and cost-effective.

Conclusions:

  • A validated, simple, and cost-effective classification for sub-endometrial vascularization has been established.
  • The high inter-observer agreement supports the reliability of this Power Doppler quantification method.
  • Further exploration of this method's clinical relevance is warranted.
