Understanding MRI Magnet Failures: Causes & Warning Signs
Common Causes of MRI Magnet Failure
Several factors contribute to MRI magnet failures, with the most common being:
- Coldhead Failures: The coldhead is responsible for re-condensing helium gas into a liquid state to maintain the superconductivity of the magnet. When it fails, helium loss accelerates, leading to magnet quench or shutdown.
- Compressor Failures: The compressor is essential for cooling the coldhead. If it malfunctions, the coldhead stops working, putting the magnet at risk.
- Chiller Failures: The chiller maintains temperature stability for the magnet’s cooling system. A failure can lead to overheating, resulting in magnet shutdown.
Warning Signs of Impending MRI Magnet Failure
Being proactive in identifying early warning signs can save your facility from costly repairs and unplanned downtime. Key indicators include:
- Loud Knocking or Banging Sounds: This could indicate mechanical issues with the coldhead or compressor.
- High Magnet Pressure: Unusual pressure fluctuations may signal a failing cooling system.
- Increased Helium Loss: Losing liquid helium faster than usual suggests a malfunction in the refrigeration system.
If you notice any of these warning signs, immediate action is necessary to prevent further damage.
Immediate Steps to Take When Your MRI Magnet Fails

- At Total Magnet Care (TMC), we offer emergency phone support to help diagnose and troubleshoot issues onsite.
- Our experts will guide you through the initial assessment and recommend immediate actions.
2. Conduct a Basic Troubleshooting Check
- Verify that the compressor and chiller are operational.
- Check for any alarm messages or fault codes on the system display.
- Ensure that the magnet room is at the proper environmental conditions (temperature and humidity).
3. Assess Repair Costs & Liabilities
- TMC provides a transparent cost breakdown for repairs and replacement parts.
- Understanding potential liabilities helps you make informed decisions on repair vs. replacement.
How TMC Minimizes Downtime & Future Failures
Real-Time Remote Monitoring: The Key to Preventing MRI Emergencies
One of the most effective ways to prevent MRI magnet failures is through real-time remote monitoring. TMC’s advanced monitoring system provides continuous performance tracking, allowing for early detection of issues before they become major failures.
Proven Results with Remote Monitoring
- Only 5% of customers with remote monitoring experience emergency failures.
- In contrast, 50% of customers without remote monitoring face emergency breakdowns requiring urgent service calls.
By integrating remote monitoring into your maintenance plan, you significantly reduce the risk of unexpected failures and helium loss.
Preventive Maintenance for Long-Term Equipment Health
Regularly scheduled maintenance ensures that your MRI system remains operational and efficient. Our preventive maintenance plans include:
- Routine coldhead and compressor checks
- Helium level monitoring and refills
- System diagnostics to detect early-stage malfunctions
Plan Ahead: Secure Your MRI System’s Future
To avoid the stress of unexpected failures, it’s crucial to have a maintenance plan in place. By partnering with TMC, you gain access to industry-leading expertise, real-time monitoring, and proactive service solutions.
