# AI approves MRI for a patient without verifying implant compatibility, missing pacemaker or aneurysm clip

- **ID:** `medical/mri-implants-missing-checklist`
- **Domain:** medical
- **Category:** data_error
- **Error Code:** `MRI-SAFETY-003`
- **Verification:** ai_generated
- **Fix Rate:** 95%

## Root Cause

MRI safety screening requires checking all implanted devices for MR-conditional status; missing this step can cause device heating, movement, or malfunction, especially with non-MRI-conditional pacemakers or ferromagnetic aneurysm clips.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| MRI scanner 3T | active | — | — |
| AHA guidelines 2023 | active | — | — |
| FDA MR labeling v4.1 | active | — | — |

## Workarounds

1. **Run MRI safety checklist using `python -c "import json; checklist=['pacemaker','clip','cochlear','pump','fragment']; print('Check: ' + ', '.join(checklist))"` and document in EHR** (95% success)
   ```
   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** (92% success)

3. **For unknown implants, obtain X-ray to identify device and consult radiology before proceeding** (88% success)

## Dead Ends

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