Why MRI Safety Is a Big Deal for Cochlear Implant Users
Magnetic Resonance Imaging (MRI) is a critical diagnostic tool used for everything from head scans to joint pain assessments. But for cochlear implant recipients, MRI safety can present a unique challenge—especially when implants use strong magnets that interact with the MRI’s magnetic field.
That’s why the magnet design of your implant matters more than you might think.
At Cochlear Implants by The Listening Lab, we offer Advanced Bionics’ HiRes™ Ultra 3D cochlear implants, designed with a multi-magnet system that not only enhances comfort but simplifies MRI access without additional surgery. Let’s break down why this matters—and how it compares to alternatives in the market.
The HiRes™ Ultra 3D Advantage: A Magnet That Moves with You
Unlike earlier or simplified single-disc magnet designs, which are still used in various forms by Cochlear and MED‑EL, the HiRes™ Ultra 3D implant features four magnetic rods in a friction-free rotating frame. This allows the magnet to align itself in three dimensions, regardless of the MRI’s orientation.
Why is that important?
- Low Torque = Less Pain:
When a magnet resists the MRI field, it creates torque, causing discomfort—or even pain—for the patient. The multi-magnet system in AB’s HiRes™ Ultra 3D dramatically reduces this torque. - No Need for Head Positioning Tricks:
In certain implant designs or earlier models, patients may have been instructed to position their heads in specific ways to reduce discomfort during MRI—but this is generally no longer required with newer devices from major manufacturers. - Fewer MRI Limitations:
Advanced Bionics’ magnet can endure up to 200 MRI scans without affecting function or needing surgical removal. Cochlear allows for 10 MRIs; MED-EL does not specify a clear threshold.
Competitor Comparison: Single Disc vs. 3D Magnet Design
| Feature | Advanced Bionics (HiRes Ultra 3D) | Cochlear (Nucleus Profile Plus) | MED-EL (Synchrony 2) |
| Magnet Type | Multi-magnet, rotates in 3D | Single disc, rotates in 2D | Single disc, rotates in 2D |
| MRI Compatibility | Up to 200 MRIs¹⁰ | Up to 10 MRIs¹¹ | Not specified |
| Torque/Discomfort | Low torque, less discomfort⁹ | May cause discomfort⁸ | Variable torque⁸ |
| Magnet Removal for MRI | Rarely needed | Possible in some cases¹² | Not specified |
Only Advanced Bionics offers a 3D rotating multi-magnet assembly that dramatically enhances both safety and convenience.
What Does This Mean for You as a Patient?
Whether you’re a child, adult, or caregiver, the ability to undergo MRIs without discomfort or additional procedures is a quality-of-life issue. No one wants to face surgery just to remove a magnet—or sit through an MRI in pain.
With HiRes™ Ultra 3D, you get:
- Comfort during the scan—thanks to reduced magnetic resistance.
- No need for magnet removal surgeries—saving you time, money, and healing.
- Fewer scan restrictions—MRIs become a routine option, not a major obstacle.
- Peace of mind—knowing your device is designed for modern medical care.
MRI-Compatible Doesn’t Always Mean Hassle-Free
Some implant providers claim “MRI compatibility,” but don’t mention the practical restrictions—such as head positioning requirements, scan limits, or magnet dislodgement risks.
With Advanced Bionics, what you see is what you get:
A system designed for real-world use, frequent scans, and minimal disruption.
This matters more than ever as diagnostic imaging becomes a bigger part of proactive healthcare in Singapore.
Final Thoughts: Choose Technology That Moves with You
Medical technology should evolve with your needs—not stand in the way of them. The multi-magnet design of the HiRes™ Ultra 3D from Advanced Bionics is a prime example of smart innovation that makes life easier for patients.
At Cochlear Implants by The Listening Lab, we ensure that your implant experience—before, during, and long after surgery—is rooted in safety, comfort, and convenience.
