What is MR Conditional? This risk is increased when objects, such as implants and other medical devices or coil cables, are present in the tunnel (bore) of the MRI scanner. Maximum spatial gradient magnetic field of 1000 Gauss/cm (10 T/m). The value of the information gained from the magnetic resonance images should be weighed against the risks of the exam for each individual patient.

MARLTON, N.J.-- (BUSINESS WIRE)-- Impulse Dynamics, a company dedicated to improving the lives of people with heart failure (HF), today announced the U.S. Food and Drug Administration (FDA) has approved the conditional use of Magnetic Resonance Imaging (MRI) for Optimizer ® CCM® delivery systems. MR Conditions of Use Medtronic SureScan systems are MR Conditional, and as such are designed to allow patients to undergo MRI under the specified conditions for use. Even so, every technologist should be aware of the potential sources of adverse events in the MR environment: With careful attention to safety procedures, these adverse events are almost entirely preventable.

FDA Determined The term “MRI-conditional” is used for devices that have no known hazards in a specific MRI environment under specific device and MRI scanner conditions. MR procedures are strictly contraindicated in patients with certain cochlear implants because of the possibility of injuring the patient and/or permanently damaging or altering the function of the cochlear implant devices and/or electrode arrays. Non-clinical testing of the worst-case scenario has demon- strated the articles of the system are MR conditional. Physicians from the Department of Radiology and the electrophysiology group in the Division of Cardiovascular Diseases at Mayo Clinic in Arizona and Minnesota devised a pilot protocol for patients with standard pacemakers in whom MRI was the preferred imaging modality: 1. After device interrogation, prospective patients met with an electrophysiologist to determine whether the patient was pacemaker dependent and the relative need for pacing under baseline conditions. The labeling of devices as MR Safe, MR Conditional, and MR Unsafe is important for ensuring the well-being of a patient with an implant in the magnetic resonance environment and avoiding serious injury. Items bearing the MR CONDITIONAL icon should include additional information on the label, as to what the conditionality of use is, such as a gauss-line restriction or SAR level limitation.
