From the Guidelines
Yes, an MRI can be performed with titanium implants, as titanium is non-ferromagnetic and does not pose a significant risk in the magnetic field of an MRI machine. When considering MRI safety, it's crucial to distinguish between ferromagnetic and non-ferromagnetic materials, as ferromagnetic objects can be hazardous in the MRI environment due to the strong magnetic field 1. Titanium, being non-ferromagnetic, is generally safe for MRI procedures, including those with implants such as joint replacements, dental implants, surgical plates, screws, and rods. However, it's essential for patients to inform their healthcare provider and MRI technologist about any implants before undergoing an MRI, as some implants may contain small amounts of other metals or components that could potentially interact with the magnetic field.
- Key considerations for MRI with titanium implants include:
- Informing healthcare providers about the presence of any implants
- Potential for localized image distortion or artifacts around the implant
- The need for radiologists to account for these artifacts when interpreting images
- Advances in modern MRI techniques that can help minimize artifacts and improve image quality around implants. While the provided study 1 focuses on cardiovascular magnetic resonance in adults with congenital heart disease, its discussion on metallic objects and implantable devices provides relevant insights into the safety of MRI procedures with various types of implants, including those made from titanium.
From the Research
MRI Compatibility with Titanium Implants
- Titanium implants are generally considered safe for MRI procedures, but certain precautions must be taken to minimize artifacts and ensure patient safety 2, 3.
- The presence of titanium implants can cause significant artifact, which may limit the diagnostic capability of MRI, but techniques such as appropriate patient positioning, attention to MRI parameters, and selection of sequences can help minimize these artifacts 2.
- Studies have shown that titanium implants produce less artifact on MRI and CT images compared to other metals such as stainless steel 4, 5.
Imaging Artifacts with Titanium Implants
- Titanium implants can cause artifacts on MRI and CT images, but the amount of artifact is generally less than that caused by other metals 4, 5.
- The use of titanium implants can result in better diagnostic quality images compared to stainless steel implants 5.
- Carbon fiber-reinforced PEEK implants have been shown to reduce susceptibility artifacts in CT and MR imaging compared to titanium implants 6.
