# 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

- **ID:** `medical/pacemaker-mri-safety-check-failure`
- **领域:** medical
- **类别:** config_error
- **错误码:** `PM-MRI-INCOMPAT-ERR`
- **验证级别:** ai_generated
- **修复率:** 82%

## 根因

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。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| Medtronic Advisa DR v2.0 | active | — | — |
| Abbott Accent MRI v1.5 | active | — | — |
| Boston Scientific Ingevity v3.0 | active | — | — |

## 解决方案

1. ```
   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)
   ```
2. ```
   Implement a pre-MRI checklist in EHR that automatically checks device model against a curated list of conditional devices and leads; flag any mismatch
   ```
3. ```
   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

- **** — Many devices implanted after 2010 are still non-conditional; only specific models with MRI-safe labeling are compatible; leads also need to be conditional (70% 失败率)
- **** — Even if generator is conditional, older leads (e.g., Medtronic CapSureFix) may not be MRI-safe; lead heating can occur at the tip (65% 失败率)
- **** — Generic registries may be outdated or incomplete; manufacturer database is authoritative and includes firmware versions (55% 失败率)
