Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Oncology

Background:

  • Breast cancer incidence is rising, particularly in younger demographics.
  • Magnetic Resonance Imaging (MRI) is crucial for breast tumor detection and treatment planning.
  • Automated segmentation methods are needed due to increasing complexity and time constraints of manual segmentation.

Purpose of the Study:

  • To develop and evaluate an automated segmentation method for breast tumors using MRI.
  • To improve the accuracy and efficiency of breast tumor segmentation.

Main Methods:

  • A combined Convolutional Neural Network (CNN) and Support Vector Machine (SVM) network was proposed.
  • The CNN extracts features, and the SVM classifies these features for segmentation.
  • The network was trained and tested on a collected breast tumor dataset.

Main Results:

  • The proposed CNN-SVM network achieved high performance metrics: 0.93 (DSC coefficient), 0.95 (PPV), and 0.92 (sensitivity).
  • Comparative analysis showed superior performance over existing segmentation frameworks.
  • The method demonstrated accurate and efficient segmentation of breast tumors.

Conclusions:

  • The CNN-SVM network provides effective breast tumor segmentation from MRI data.
  • The method adapts to variations in breast tumors, ensuring accurate and efficient segmentation.
  • This approach holds significant potential for future identification of triple-negative breast cancer.
