Aspiration biopsy guided with computed tomography (CT) has long been a valuable tool in the evaluation of head and neck disease. The ability to obtain diagnoses without the need for surgery has had a significant effect on patient treatment. Magnetic resonance (MR) imaging is now rapidly replacing CT as the primary imaging study for many head and neck diseases. The standard stainless steel needles used for CT-guided biopsy are unsuitable for MR-guided biopsy because significant ferromagnetic artifacts obscure the underlying anatomy. A new needle has recently been designed specifically for use with MR imaging. This needle has far less magnetic susceptibility and therefore does not cause significant image distortion. The authors describe the use of this needle in MR-guided aspiration biopsy of a variety of lesions in the head and neck.
计算机断层扫描（CT）引导下的穿刺活检长期以来一直是评估头颈疾病的重要工具。无需手术即可获得诊断的能力对患者治疗产生了重大影响。如今，磁共振（MR）成像正迅速取代CT，成为许多头颈疾病的主要影像学检查方法。用于CT引导活检的标准不锈钢针不适合用于MR引导活检，因为显著的铁磁伪影会掩盖潜在的解剖结构。最近专门设计了一种新针，用于磁共振成像。这种针的磁化率要低得多，因此不会造成明显的图像失真。作者描述了这种针在MR引导下对头颈部各种病变进行穿刺活检中的应用。
