Summary
Interventional MRI enables precise breast lesion marking and biopsy. MR-guided tumor ablation shows promise for breast cancer treatment, but further research is needed for margin control and accurate imaging in all tissue types.
Area of Science:
- Medical imaging
- Interventional radiology
- Oncology
Background:
- Interventional magnetic resonance (MR) imaging techniques are increasingly available for preoperative needle localization and lesion marking.
- Minimally invasive MR-guided core biopsy has shown potential but faces limitations with small lesions.
Purpose of the Study:
- To evaluate MR-guided tumor ablation as a breast-conserving therapy for breast cancer.
- To assess the efficacy of MR-guided ablation in controlling tumor margins compared to surgery.
Main Methods:
- Utilizing interventional MR-guided techniques for needle localization, lesion marking, and core biopsy.
- Investigating MR-guided tumor ablation as a novel treatment modality.
- Exploring MR imaging's ability to map heating during ablation for margin control.
Main Results:
- MR-guided ablation is emerging as a promising treatment, aligning with breast conservation trends.
- Challenges remain in accurately assessing the extent of disease, particularly ductal carcinoma in situ.
- Limitations exist with conventional MR thermometry (proton resonance frequency shift method) in breast tissue, necessitating alternative methods like T1 and T2 measurements.
Conclusions:
- MR-guided ablation holds potential for breast cancer treatment, but further studies are required to confirm its effectiveness in achieving surgical margin control.
- Accurate MR imaging of heating extent is crucial for successful ablation, and alternative thermometry techniques are under investigation due to limitations of current methods in breast tissue.
