Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Oncology

Background:

  • High breast density (PBD) is linked to increased breast cancer incidence.
  • Mammography for PBD assessment is subjective, necessitating objective measurement techniques.
  • Bioimpedance analysis offers a potential objective method for PBD evaluation.

Purpose of the Study:

  • To introduce and evaluate a novel bioimpedance-based method, the anomalies tracking circle (ATC) algorithm, for objective breast density measurement.
  • To assess the correlation between bioimpedance measurements and breast density determined by mammography.
  • To explore the potential of the ATC algorithm as an auxiliary tool for breast cancer risk assessment.

Main Methods:

  • Breast bioimpedance measurements were taken from thirteen female participants.
  • Mammograms were acquired immediately following bioimpedance measurements for comparison.
  • The anomalies tracking circle (ATC) algorithm was applied to bioimpedance data to analyze breast density variations.

Main Results:

  • The anomalies tracking circle (ATC) algorithm demonstrated variations corresponding to different breast densities.
  • Classification techniques utilizing ATC data proved effective in determining percentage of breast density (PBD).
  • A correlation was observed between bioimpedance-derived metrics and mammographically assessed breast density.

Conclusions:

  • The bioimpedance-based ATC method provides a promising approach for objective breast density evaluation.
  • This technique may serve as a valuable adjunct to mammography, enhancing the precision of breast density assessment.
  • Objective PBD measurement can contribute to more accurate breast cancer risk stratification.
