This article explores minimally invasive breast tumor therapy guided by MR imaging. It covers technical challenges, treatment options like cryotherapy and focused ultrasound, and ethical considerations for clinical trials.

Area of Science:

  • Oncology
  • Radiology
  • Medical Engineering

Background:

  • Minimally invasive therapies offer alternatives to traditional breast cancer surgery.
  • Magnetic Resonance (MR) imaging provides detailed anatomical and functional information crucial for guiding interventions.

Purpose of the Study:

  • To review the integration of MR imaging with minimally invasive therapeutic techniques for breast tumors.
  • To identify technical challenges and discuss current treatment modalities and future directions.

Main Methods:

  • Discussion of technical aspects including margin assessment, detection of ductal carcinoma in situ (DCIS), and precise localization.
  • Overview of therapeutic modalities: cryotherapy, interstitial hyperthermia, and focused ultrasound.
  • Review of current clinical application and ethical considerations.

Main Results:

  • Accurate margin determination and lesion localization remain key technical hurdles.
  • Various minimally invasive techniques show promise for breast tumor treatment.
  • Limited data exists on the extent of minimally invasive therapy performed to date.

Conclusions:

  • MR imaging-guided minimally invasive therapy is a developing field for breast tumors.
  • Addressing technical challenges is crucial for wider clinical adoption.
  • Further research and ethical deliberation are needed for clinical trials and widespread use.
