What Are MRI Side Effects?
MRI scans are generally safe, but some people experience mild side effects. Most are temporary and resolve quickly.
The most frequently reported side effects include:
- Feeling or being sick (nausea)
- A skin rash
- A headache
- Dizziness
These side effects are typically mild and short-lived. (Source: NHS)
Side Effects of Contrast Material
If a contrast agent (dye) is injected during your MRI, there's a small chance of experiencing additional side effects. These can range from mild reactions like:
- Mild rashes and hives (Source: Medical News Today)
- Itching (Source: Johns Hopkins Medicine)
to more serious, though rare, allergic reactions. Patients are often monitored for a short period after receiving contrast to watch for any reactions. (Source: Johns Hopkins Medicine)
Rare Side Effects and Considerations
While rare, some individuals might experience a warming sensation or tingling during the scan.

It's important to inform your doctor about any medical devices or implants you have before undergoing an MRI scan.
