MRI Safety 1 – Implants Questions and Answers Latest Update Already Passed

MRI Safety 1 – Implants Questions and Answers Latest Update Already Passed What is the main concern with metallic implants in MRI? They can heat up, move, or cause artifacts in the image Why should a patient with a pacemaker be carefully screened before an MRI? Pacemakers can be affected by the magnetic field, leading to malfunction or serious harm How does an MRI-compatible implant differ from a non-compatible one? MRI-compatible implants are designed to be safe in the MRI environment without risks of heating or displacement Why is it important to check the conditions of use for an implant before an MRI scan? Some implants are only safe under specific magnetic field strengths or scanning conditions What is the risk of an aneurysm clip in MRI? If not MRI-safe, it can move due to magnetic forces, potentially causing severe injury 2 Why are cochlear implants a concern in MRI? They can heat up, malfunction, or cause significant artifacts in imaging What precaution should be taken if a patient has an orthopedic implant? The implant’s MRI safety labeling should be verified to determine if it is safe at the scanning parameters Why must patients with neurostimulators be evaluated before an MRI? Neurostimulators can be affected by the magnetic field, causing unintended electrical stimulation or device damage What can happen if an MRI is performed on a patient with a non-MRI-safe cardiac stent? The stent may shift, heat up, or interfere with the quality of the scan Why are bullet fragments and shrapnel a concern in MRI? They may contain ferromagnetic materials that could move or heat up, causing tissue damage 3 What is the significance of "MR Conditional" labeling on implants? It means the device is safe only under specific MRI conditions, such as a limited field strength or scanning duration Why should patients with programmable shunts consult their physician before MRI? The magnetic field may alter the settings of the shunt, affecting its function How does MRI affect insulin pumps? The magnetic field can damage electronic components, making the device unreliable What should be done if a patient has an unknown implant before an MRI? Imaging or documentation review should be conducted to determine its MRI safety status Why is a thorough patient history important before MRI scanning? Undisclosed implants or foreign bodies may pose
