What type of metal is MRI safe?

By far, the most common metal used for MRI compatible equipment or tools is titanium. And for good reason. Titanium is an excellent material to make MRI-safe products because it’s lightweight and strong, in addition to being nonmagnetic.

Is surgical steel OK for MRI?

Studies done on this material using surgical staples made of the same steel produced neither heat, nor movement when put in the MRI. In other words, you’re good to go. … This grade of titanium is commonly used in dental implants and those implants are deemed safe for the MRI.

Why did my MRI hurt?

MRI is a very safe procedure. The strong magnetic field itself does not hurt people, unless they have certain types of metal implanted in their body. The magnetic field can cause certain types of metal to move, which could potentially cause an injury.
