MRI Safety MRI Safety and Compatibility

Worst-case analysis

Multicomponent medical implants consist of several parts, each with specific parameters including material properties, geometry, and physical design. This results in a large number of possible combinations, each interacting differently with the MR environment present in the bore of an MRI coil.

Performing a full evaluation of the MR safety and image compatibility for every single combination among the product portfolio of a medical device manufacturer is far beyond the economical capabilities of most manufacturers. Therefore, it becomes necessary to determine one or more so-called “worst cases”.

Such "worst cases" define the upper limits regarding the MRI safety risk for patients with an implant undergoing an MRI scan.
