Published reports of magnetic resonance (MR)-guided needle biopsy have involved low- and mid-field-strength systems because of the concern of needle artifact and risk of increased needle torque at higher field strengths. To the authors' knowledge, this is the first report of a high-field-strength (1.5-T) system used to guide aspiration cytology in the head and neck in a patient. The procedure was successfully accomplished without additional needle torque or substantial increase in image artifact relative to lower-field-strength imaging.
由于担心针伪影以及在更高场强下针扭矩增加的风险，已发表的关于磁共振（MR）引导下针吸活检的报告涉及低场强和中场强系统。据作者所知，这是第一份关于在患者头部和颈部使用高场强（1.5-T）系统引导细针穿刺抽吸活检的报告。该操作成功完成，相对于低场强成像，没有额外的针扭矩或图像伪影大幅增加。
