Breast imaging using electrical impedance tomography: correlation of quantitative assessment with visual...

Area of Science:

• Medical Imaging
• Biophysics
• Radiology

Background:

• Electrical impedance tomography (EIT) is a non-invasive, radiation-free breast screening technique.
• EIT allows for both visual interpretation and quantitative assessment of breast images.
• This study aimed to correlate quantitative and visual assessments of EIT breast images.

Purpose of the Study:

• To correlate quantitative electrical conductivity measurements with visual interpretation of breast EIT images.
• To investigate associated factors influencing breast EIT assessments.
• To establish the reliability of EIT in breast abnormality detection.

Main Methods:

• 150 mammography patients over 40 underwent EIT.
• Visual interpretation used the BI-EIM classification by an experienced radiologist.
• Quantitative assessment involved comparing breast average electric conductivity with norms and correlating with visual findings using Chi-square tests.

Main Results:

• Mean electrical conductivity in Malaysian women was significantly lower than in Caucasians (p<0.05).
• Quantitative EIT assessment showed a significant relationship with visual image interpretation (p<0.05).

Conclusions:

• Quantitative assessment of EIT images is significantly related to visual interpretation.
• EIT shows promise as a reliable tool for breast abnormality assessment.
