# AI批准患者进行MRI，未验证植入物兼容性，遗漏起搏器或动脉瘤夹

- **ID:** `medical/mri-implants-missing-checklist`

- **错误码:** `MRI-SAFETY-003`

## 根因

MRI安全检查需要确认所有植入设备的MR条件状态；遗漏此步骤可能导致设备加热、移动或故障，特别是非MRI条件起搏器或铁磁性动脉瘤夹。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| MRI scanner 3T | active | — | — |
| AHA guidelines 2023 | active | — | — |
| FDA MR labeling v4.1 | active | — | — |

## 解决方案

1. ```
   Run MRI safety checklist using `python -c "import json; checklist=['pacemaker','clip','cochlear','pump','fragment']; print('Check: ' + ', '.join(checklist))"` and document in EHR
   ```
2. ```
   Use MRI-safe implant database (e.g., www.mrisafety.com) to verify each device by model number; log query results
   ```
3. ```
   For unknown implants, obtain X-ray to identify device and consult radiology before proceeding
   ```

## 无效尝试

- **** — Only MR-conditional pacemakers (specific models from 2010+) are safe; older models or non-conditional ones can cause fatal arrhythmias or lead dislodgement (90% 失败率)
- **** — Aneurysm clips, cochlear implants, drug pumps, or metallic fragments in eyes can also be ferromagnetic and cause injury (80% 失败率)
- **** — Patients may forget or not know implant details; formal screening form and manufacturer records are required (85% 失败率)
