Methodological analysis demonstrates two classes of magnetic compatibility in surgical instruments, highlighting materials that eliminate image distortion during magnetic resonance imaging.

Key Points

To define the role of magnetic susceptibility in MRI and establish criteria for two distinct classes of material magnetic compatibility in medical devices.
Assessed the physical criteria required to prevent significant magnetic forces and torques on materials placed in an MRI scanner.
Evaluated material candidates and the influence of object shape, orientation, and demagnetizing effects on image distortion and stereotactic positional accuracy.
Defined first-kind compatibility as the absence of disruptive forces and torques, and second-kind compatibility as producing negligible image distortion and positional error.
Identified a specific group of materials that achieve second-kind compatibility without causing image distortion, even when positioned directly within the imaging field of view.
Identified pervasive discrepancies in published magnetic susceptibility data and advocated for the standardized adoption of SI units across MRI applications.
