Magnetic resonance (MR) imaging is now an accepted component of standard breast-imaging practice. This article reviews the fundamentals of performing an MR imaging-guided biopsy using a grid localization system, and discusses many of the finer points and nuances of the procedure. Tips and tricks found useful at the authors' institution are included, although multiple variations also exist. Performing effective and efficient MR imaging-guided biopsy depends both on deliberate preparation (of the proceduralist, the patient, and the equipment) and on deliberate positioning (of the patient and the sampling device).
磁共振（MR）成像如今已成为标准乳腺成像实践中被认可的一部分。本文回顾了使用网格定位系统进行MR成像引导活检的基本原理，并讨论了该操作的许多细节和细微差别。文中包含了作者所在机构发现有用的技巧和窍门，尽管也存在多种变体。要有效且高效地进行MR成像引导活检，既依赖于（操作医生、患者和设备的）精心准备，也依赖于（患者和采样设备的）精心定位。
