Yes, an MRI can affect your skin, although it is rare.
How MRI Affects Skin: Potential for Burns
While MRI scans are generally considered safe, there is a risk of skin burns, although uncommon. According to the provided reference:
- Heat Build-Up: On rare occasions, heat can accumulate in the tissues during an MRI scan.
- Burns: This heat can result in burns, primarily on the skin surface.
- Delayed Awareness: Unlike typical burns, the burning sensation during an MRI may not be immediately noticeable.
Why Burns Occur
- Metal Objects: Burns are more likely to occur if metallic objects are present in or on the body. Examples include:
- Jewelry (rings, necklaces, earrings, etc.)
- Clothing with metal fasteners
- Implants
- Tattoos with metal-based inks
- Body Position: Certain body positions can also increase the risk, such as if the skin is in contact with itself (e.g., skin-on-skin contact) and creates a loop.
Prevention is Key
Hospitals have strict protocols to minimize risks:
- Patient Screening: MRI staff will ask if you have any metal implants or foreign objects before the scan.
- Removing Metal: Patients must remove all jewelry, watches and metallic objects before the scan.
- Specialized Clothing: Patients wear MRI-safe clothing.
- Padding: Padding or spacers might be used to prevent skin-on-skin contact during the scan.
What to do if a Burn Occurs
- Report it Immediately: If you feel discomfort or notice any skin changes after an MRI, notify the medical staff immediately.
| Risk | Explanation |
|---|---|
| Burns | Heat can build up in the tissues during the scan leading to surface burns. |
| Delayed Awareness | Burns during the MRI process may not be noticeable to the patient |
Conclusion
Although the risk is minimal, MRI scans can potentially affect your skin, primarily through burns from heat build-up. However, hospitals take steps to greatly minimize this risk through proper protocols and precautions.
