Manufacturer Narrative

Siemens has completed an investigation of the reported event.The root cause was determined to be the introduction of ferromagnetic pieces into the mr examination room and therefore a user error.Due to the strong magnetic field, particular safety measures have to be adhered to in order to prevent injuries.Therefore, the magnetom prisma/prisma fit operator manual - mr system syngo mr e11 section 2 and the magnetom prisma/prisma fit system owner manual section 1 provide clear instructions and warnings regarding both magnetic field hazards and training of personnel with regards to mr safety.The responsibility to instruct personnel and patients who have access to the mr examination room about magnetic field hazards lies with the customer.The manuals state that only equipment specified or recommended for use in the controlled area (mr examination room) shall be used.The introduction of magnetic objects into the magnetic field is contrary to the statements given in the operating instructions.Furthermore, special warning signs are posted at the entrance of the controlled access area.The manufacturer is not considering further actions resulting from this event as no systematic error has been recognized.
