OBJECTIVE
The recent approval of an "MR-conditional" pacemaker system by the U.S. Food and Drug Administration allows patients with that pacemaker system to undergo MRI examinations within specific conditions. These examinations must be attended by radiology health care professionals with training for the use of the pacemaker system.
CONCLUSION
Radiologists should be knowledgeable of the specific limitations with regard to patient isocenter and coil positioning within the required 1.5-T MR system and the importance that the pacer be programmed before and after scanning.
目的
美国食品和药物管理局最近批准了一种“磁共振条件下（MR-conditional）”起搏器系统，允许使用该起搏器系统的患者在特定条件下进行磁共振检查。这些检查必须由接受过起搏器系统使用培训的放射科医疗保健专业人员进行。
结论
放射科医生应该了解患者在所需 1.5T 磁共振系统中与等中心和线圈定位相关的具体限制，以及在扫描前后对起搏器进行编程的重要性。
