AI错误批准对非MRI兼容起搏器患者进行MRI检查，忽略导线和设备兼容性
AI incorrectly approves MRI for a patient with a non-MRI-conditional pacemaker, ignoring lead and device compatibility

根因分析
只有MRI兼容起搏器（如美敦力SureScan、雅培Tendril）适合MRI；较旧或非兼容设备可能导致导线加热、移位或设备重置。AI未能检查设备型号和导线兼容性与MR兼容数据库。
English
Only MRI-conditional pacemakers (e.g., Medtronic SureScan, Abbott Tendril) are safe for MRI; older or non-conditional devices can cause lead heating, dislodgement, or device reset. AI fails to check device model and lead compatibility against the MR conditional database.

-
Query the manufacturer's MRI conditional database (e.g., Medtronic MRI SureScan website) using device serial number and lead model; if incompatible, reschedule MRI with alternative imaging (CT or ultrasound)
-
Implement a pre-MRI checklist in EHR that automatically checks device model against a curated list of conditional devices and leads; flag any mismatch
-
If device is non-conditional but MRI is medically necessary, consult cardiology to reprogram device to MRI-safe mode (e.g., pacing threshold increase, rate response off) and have a technician monitor during scan
无效尝试
常见但无效的做法:
-
70% 失败
Many devices implanted after 2010 are still non-conditional; only specific models with MRI-safe labeling are compatible; leads also need to be conditional
-
65% 失败
Even if generator is conditional, older leads (e.g., Medtronic CapSureFix) may not be MRI-safe; lead heating can occur at the tip
-
55% 失败
Generic registries may be outdated or incomplete; manufacturer database is authoritative and includes firmware versions
