这项研究的重点是心胸 MRI 扫描期间心外膜和心内膜引线长度不同的儿童和成人心脏植入电子设备 (CIED) 射频引起的加热的潜在风险。婴儿和幼儿是心外膜 CIED 的主要接受者，但由于数据有限，这些设备尚未被 FDA 批准为有条件的 MR，导致儿科医院要么拒绝为大多数儿科 CIED 患者提供 MRI 服务，要么根据成人研究的结果采用全扫描策略。该研究认为，风险收益决策应根据个人情况做出。我们在成人和儿童拟人模型中使用了 120 个临床相关的心外膜和心内膜设备配置，以确定 1.5 T 射频暴露期间的温升。结果表明，在儿童模型中，心外膜引线的射频加热明显高于心内膜引线，但在成人模型中则不然。此外，身体尺寸和导联长度显着影响射频加热，在基于心外膜导联较短的年幼儿童的模型中观察到射频加热高达 12°C。该研究提供了有关 CIED 射频引起加热的循证知识，并强调了在评估儿科 CIED 患者 MRI 扫描的潜在风险时做出个人风险效益决策的重要性。
This study focused on the potential risks of radiofrequency-induced heating of cardiac implantable electronic devices (CIEDs) in children and adults with epicardial and endocardial leads of varying lengths during cardiothoracic MRI scans. Infants and young children are the primary recipients of epicardial CIEDs, though the devices have not been approved as MR conditional by the FDA due to limited data, leading to pediatric hospitals either refusing the MRI service to most pediatric CIED patients or adopting a scan-all strategy based on results from adult studies. The study argues that risk–benefit decisions should be made on an individual basis. We used 120 clinically relevant epicardial and endocardial device configurations in adult and pediatric anthropomorphic phantoms to determine the temperature rise during RF exposure at 1.5 T. The results showed that there was significantly higher RF heating of epicardial leads than endocardial leads in the pediatric phantom, but not in the adult phantom. Additionally, body size and lead length significantly affected RF heating, with RF heating up to 12 °C observed in models based on younger children with short epicardial leads. The study provides evidence-based knowledge on RF-induced heating of CIEDs and highlights the importance of making individual risk–benefit decisions when assessing the potential risks of MRI scans in pediatric CIED patients.
