  • a MRI conditional are devices that are MRI safe under a very specific set of conditions/MRI settings provided in the labeling.

  • b Patients can safely undergo magnetic resonance (MR) scanning based on the following MR specifications established through nonclinical testing: (1) static magnetic field of 1.5 and 3.0 Tesla only, (2) specified maximum spatial gradient magnetic field (implant specific), and (3) maximum MR system reported, whole body averaged specific absorption rate of 2 W/kg in normal operating mode.
