Intraprocedural magnetic resonance imaging-guided interventions in the breast

Despite the proven high sensitivity of magnetic resonance imaging (MRI) for invasive breast cancer, MRI has lagged behind mammography and sonography as an imaging modality for guiding interventional procedures because of the lack of suitable techniques. New imaging apparatuses, pulse sequences, and MR-compatible devices are beginning to enable MRI-guided breast interventions, including preoperative lesion localization and minimally invasive biopsy. MR-guided tumor ablation holds promise as a future therapy for breast cancer because of the ability of MRI to reveal the progress of heating and freezing, as well as the extent of ablated tissue.
