Some implanted devices are labeled as “MR conditional.” Depending on the specific conditions, a desired exam may be precluded, or only allowable under suboptimal conditions. For example, there may be limitations on the gradient slew rate or static field, which are more stringent than the standard regulatory limits in the absence of the implant. Recently, compact 3T (C3T) MR was introduced with high-performance gradients. It is shown that for brain imaging, the safety conditions for some implants may be satisfied at the location of the implant, while the full imaging performance of the C3T is available to image the brain.
