UNLABELLED
Magnetic resonance imaging (MRI)-guided interventions, including biopsies and wire localizations, are fundamental to any breast imaging practice due to the high sensitivity but limited specificity of breast MRI. The basic steps of MRI-guided biopsies are similar regardless of the vendor or platform, and technical considerations include approach planning, patient preparation and positioning, lesion targeting, and directional sampling using a vacuum-assisted biopsy technique. Unique challenges related to MRI-guided biopsies include vanishing lesions due to contrast washout, obscuration of the biopsy site due to susceptibility artifacts, and limited access to posteromedial lesions. A careful approach to planning, patient positioning, and lesion targeting will maximize the chances for a successful biopsy. Due to overlapping imaging features between benign and malignant lesions, radiologic-pathologic concordance is difficult and essential for further patient management.

磁共振成像（MRI）引导介入，包括活检和导丝定位，由于乳腺 MRI 的高灵敏度但特异性有限，因此是任何乳腺影像实践的基础。无论供应商或平台如何，MRI 引导活检的基本步骤都相似，技术考虑因素包括方法规划、患者准备和定位、病变定位以及使用真空辅助活检技术进行定向采样。与 MRI 引导活检相关的独特挑战包括由于对比冲洗而导致的病变消失、由于磁化率伪影导致的活检部位遮挡以及对后内侧病变的有限访问。仔细规划、患者定位和病变定位将最大限度地提高活检成功的机会。由于良性和恶性病变之间存在重叠的影像学特征，放射病理学一致性很困难，对于进一步的患者管理至关重要。
