Why titanium blades are preferred to steel blades in MRI assisted surgeries

MRI assisted surgery

Magnetic Resonance Imaging (MRI) assisted surgeries, also known as Image-guided surgeries uses high-definition cameras and electromagnetic fields to view structures in a person body in three dimensions. This technique allows surgeons to reach tumors that were previously thought to be inoperable due to their location. 

During an MRI assisted surgery, traditional steel blades are generally not used because they can be drawn to the MRI machine which contains a very large and strong magnet. This can damage the machine and also cause image artifacts on the scans. As an alternative, titanium, diamond and ceramic scalpel blades are preferred.

Other imaging techniques that could be used during image guided surgeries are computed tomography (CT) and positron emission tomography (PET).
