A new breast coil allows magnetic resonance (MR)-guided needle localization of breast lesions. This technique enables precise needle insertion for biopsy, improving diagnosis of cancerous and benign breast conditions.

Area of Science:

  • Medical Imaging
  • Radiology
  • Breast Cancer Detection

Background:

  • Magnetic resonance (MR) imaging alone poses challenges for evaluating breast lesions.
  • Preoperative MR-guided localization is difficult due to limited breast accessibility within the MR coil.
  • Standard MR-guided core biopsy and needle aspiration are not feasible.

Purpose of the Study:

  • To evaluate a prototype localization breast coil developed with Siemens Erlangen.
  • To assess the feasibility of MR-guided needle localization for breast lesions.
  • To overcome limitations in preoperative breast lesion localization.

Main Methods:

  • A prototype localization breast coil with two plates for mediolateral breast compression was developed.
  • The coil features numerous perforations allowing bilateral breast access.

  • Sterile needle insertion is facilitated through bushings fitted into the coil's holes.

    • Main Results:

    • Precise needle insertion was achieved in 10 out of 11 lesions.
    • Successful needle insertion targeted 5 invasive carcinomas, 1 MR-detected additional focus, 2 in situ carcinomas, and 3 benign lesions.
    • The prototype demonstrated effectiveness in localizing various breast lesion types.

    Conclusions:

    • MR-guided needle localization of breast lesions is feasible with the developed prototype coil.
    • This technique enhances the ability to perform biopsies and further evaluate breast abnormalities detected by MR.
    • The study confirms the potential of MR-guided localization in breast diagnostics.
