Additionally, there may be substantial “retentive” or counter-forces provided by the presence of sutures or other means of fixation (e.g., screws, cement, etc. Information for each object has been specifically categorized using a Status designation, which indicates the object to be Safe, Conditional, or Unsafe, as follows:
The implant/device was determined to be MR Conditional according to the terminology specified in the American Society for Testing and Materials (ASTM) International, Designation: F2503. -Maximum MR system reported whole-body-averaged specific absorption rate (SAR) of 2-W/kg for 15 minutes of scanning (per pulse sequence). However, since patients’ care may require serial MRIs, it is necessary to evaluate device safety and performance after multiple scans. Nevertheless, there has been no report of patient injury in association with the presence of this device in the MR environment at the static magnetic field strength used for MR safety testing. The clinical performance of the INGEVITY lead demonstrated a high lead‐related complication‐free rate over 12 months of follow‐up and excellent electrical characteristics. Special Note: If there is any concern regarding the integrity of the implant or the integrity of the tissue with regard to its ability to retain the object in place during an MR procedure or during exposure to the MR environment, the patient or individual should not be allowed into the MR environment. To look up your patient’s system, use the Product Search tool to determine whether your patient’s device and leads are safe for an MRI. -Maximum MR system reported whole-body-averaged specific absorption rate (SAR) of 2-W/kg for 15 minutes of scanning (per pulse sequence). Non-clinical testing demonstrated that the implant/device is MR Conditional. 28, 326-328. A list of biomedical company websites may be found on this website. The main complications in MRI arise from the magnetic force and torque on the internal magnet from B0. The MR environment presents unique safety hazards for patients and other persons with medical devices near or inside an MR system.This draft guidance, when finalized, is intended to: -Maximum spatial gradient magnetic field of 720-Gauss/cm (a higher value for the spatial gradient magnetic field may apply if properly calculated).
