MR imaging-guided interventions in the breast

Area of Science:

• Radiology and Imaging Science
• Oncology
• Surgical Pathology

Background:

• Breast magnetic resonance (MR) imaging demonstrates high sensitivity in identifying invasive breast cancer.
• A significant challenge in breast MR imaging is the presence of benign enhancing lesions that can mimic malignancy, leading to false positives.
• Accurate differentiation between benign and malignant enhancing lesions is critical for appropriate patient management and avoiding unnecessary invasive procedures.

Purpose of the Study:

• To discuss the techniques, potential pitfalls, and clinical indications for MR imaging-guided needle localization.
• To explain the application of percutaneous biopsy under MR guidance for characterizing breast lesions.
• To highlight the importance of MR-guided biopsy in improving the specificity of breast cancer diagnosis.

Main Methods:

• Review of techniques employed in MR imaging-guided needle localization procedures.
• Discussion of common challenges and pitfalls encountered during MR-guided biopsies.
• Analysis of clinical scenarios where MR-guided needle localization and biopsy are indicated.

Main Results:

• MR imaging-guided needle localization provides precise targeting for biopsy of suspicious breast lesions.
• Percutaneous biopsy under MR guidance allows for histological sampling of non-palpable or mammographically occult lesions.
• This approach aids in reducing false-positive diagnoses by obtaining tissue confirmation of enhancing lesions.

Conclusions:

• MR imaging-guided needle localization and percutaneous biopsy are essential tools for differentiating benign from malignant enhancing breast lesions.
• These techniques enhance the diagnostic accuracy of breast MR imaging, guiding definitive treatment decisions.
• Integration of MR-guided biopsy into clinical practice improves patient outcomes by enabling targeted tissue diagnosis.
