Background: Advancements in breast cancer detection have led to a growing number of patients with nonpalpable breast conditions choosing breast-conserving surgery for early-stage disease. While most early-stage breast cancers are detected as small nonpalpable cancers by screening mammography and ultrasound, a subset of these cancers may have additional disease extent that cannot be detected by mammography and ultrasound alone. Although MRI-guided localization is infrequently carried out without a simultaneous tissue biopsy, there are scenarios encountered where localization of MRI disease extent without biopsy may help facilitate improved breast conservation surgery outcomes. Recently, a cutting-edge approach known as single-step wireless MRI-guided breast localization utilizing radar reflectors has emerged. This technique uses wireless technology and MRI to accurately mark and locate suspicious breast lesions, offering numerous benefits over traditional wire localization methods, especially in surgical planning before treatment.
Learning Objectives: 1. Review the indications and alternatives to MRI guided localization 2. Review the risks and benefits of MRI guided pre-surgical localization 3. Technique | Understand the technical steps employed for successful MRI guided non-wire guided localization
Abstract Content/Results: This will be a pictorial review of MRI-guided single step pre-surgical localization using non-wiier localization devices. The following topics will be explored.
We will provide an overview of MRI -guided pre-surgical localization using non-wire localization devices. • Indications for MRI-guided localization • Alternatives to Wireless MRI-guided localization • Procedure technique for wireless localization • Preparation, Positioning and Targeting • Case-based examples with tips for successful MRI-guided localization using wireless devices
Conclusion: The utility of contrast-enhanced breast Magnetic Resonance Imaging (MRI) in the detection of mammogram and ultrasound occult breast cancer, particularly in high-risk patient population has demonstrated efficacy in recent years. Wireless MRI-guided localization is a valuable and practical technique for localizing disease extent where a component of disease can only be seen by MRI. This technique can be employed by breast radiologists with minimal additional technical training and can serve as an additional strategy for pre-surgical localization in patients desiring breast conservation.
