This study shows that Strain-Encoded (SENC) MRI can detect stiff breast masses with as little as 7% tissue compression. This technique aims to improve breast cancer screening accuracy and patient comfort during MRI exams.

Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Oncology

Background:

  • Breast cancer is a leading cause of death in women, necessitating accurate screening methods.
  • Diagnostic magnetic resonance imaging (MRI) is crucial for high-risk patient screening.
  • Strain-Encoded (SENC) MRI enhances specificity by assessing tissue stiffness.

Purpose of the Study:

  • To determine the minimum tissue compression required for SENC MRI to detect and classify breast masses.
  • To optimize SENC MRI for in-vivo application, improving patient comfort and diagnostic accuracy.

Main Methods:

  • Utilized finite element method (FEM) simulations.
  • Conducted phantom experiments to validate simulation results.
  • Investigated varying levels of tissue compression for SENC imaging.

Main Results:

  • SENC MRI successfully detected stiff masses at a 7% compression level.
  • Higher compression levels (beyond 7%) are necessary to differentiate between normal, benign, and malignant masses.
  • On-line SENC calculations on the scanner console enable adaptive compression levels.

Conclusions:

  • Reduced compression levels for SENC MRI are feasible for detecting stiff breast masses.
  • A strategy of starting with low compression and increasing as needed enhances patient comfort and diagnostic potential.
  • This approach could improve the specificity and efficacy of breast cancer screening using MRI.
