Two hospital workers spent four hours pinned between a highly magnetic MRI machine and a metal oxygen tank. Mop buckets, vacuum cleaners, IV poles, oxygen tanks, patient stretchers, heart monitors and countless other objects have all been pulled into the magnetic fields of MRI machines. A news feed for Health Care Professionals (HCPs), reviewing latest medical research and approvals. November 10, 2005, 2:31 AM ... NessAiver said the cardinal rule for MRI safety is that no iron-like metal be allowed in the MRI room. That patient, a 60-year-old man, sustained fractures to his face when an oxygen canister became wedged in the machine pressing against his head. MRI is a ubiquitous medical imaging technology typically using superconductivity to generate a strong, homogeneous, and generally ceaseless magnetic field. Frank Shellock, MD, an MRI safety expert who has been tracking MRI-related accidents for 16 years tells WebMD that this is the first death caused by an MRI projectile, and that any kind of MRI accident is "relatively rare.". While accidents involving the magnetized machines are rare, they do happen. There have been a number of accidents where unsecured metal objects, such as mops or oxygen cylinders, were pulled towards the MRI scanner when the magnetic field was turned on, resulting in the person in the scanner being injured. Projectile cylinder accidents resulting from the presence of ferromagnetic nitrous oxide tanks in the MR suite. How MRI Scans and Metals Interact. The magnetic field an MRI generates is 30,000 times stronger than that of the earth, capable of accelerating an object the size of an oxygen canister to dozens of feet per second. They involved patients with metal implants, which the MRI magnet can dislodge or damage. Mechanical events. Operators insist that metal objects be kept out of the MRI room. Projectile accidents with dental crowns and MRI are by far the most frightening.
